The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
The slope of the line that passes through the points (-2, 12) and (4, -15) is -27/6
The y-intercept of the line that passes through the points (-2, 12) and (4, -15) is 3
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
The equation of a line is y = mx + c.
The slope can be calculated.
Slope = (d - b) / )(c - a)
Where (a, b) and (c, d) are the two points on the line.
The line passes through (-2, 12) and (4, -15)
This means,
Slope = (-15 - 12) / (4 + 2) = -27 / 6
m = -27/6
The line passes through the point (-2, 12).
12 = -27/6 x -2 + c
12 = 9 + c
c = 12 - 9
c = 3
Thus,
The slope of the line that passes through the points (-2, 12) and (4, -15) is -27/6
The y-intercept of the line that passes through the points (-2, 12) and (4, -15) is 3

The the direction of the resultant force is A. approximately 37.33° above the ground.
What's a resultant force?A resultant force simply means the single force that has same effect as two or more forces that are acting together.
In this case, a student pulls with a force of 40 pounds at an angle of 30° above the ground, and the other student pulls with a force of 35 pounds at an angle 45° above the ground.
The direction of the resultant force is 37.33° above the ground.

Sarah started 3 miles below the rim of the canyon and hiked until she was 8 miles above the rim. Her brother Sam said she hiked 5 miles. Sarah said she hiked 11 miles.
Who is correct and why?
A. Sam is correct because |3 – 8| = 5.
B. Sam is correct because |–3 – 8| = 5.
C. Sarah is correct because |–3 + 8| = 11.
D. Sarah is correct because |–3 – 8| = 11.
Answer:
D
Step-by-step explanation:
We can assume that the rim of the canyon is 0. Sarah started 3 miles below, so -3, BUT distance can never be negative, so it's considered 3 miles. Then, she went 8 miles above zero. So the 3 miles she went before reaching the rim plus the 8 miles she went after reaching the rim equals 11 miles.
So now we know that Sarah is right, but how do we know which equation is correct? Well, if we look at option C:
[tex]|-3+8|=11[/tex]
When solving absolute value, we solve everything within the absolute value before applying the absolute value. This means that we add -3+8 first, which equals 5, and then apply absolute value, which still equals 5. This equation is not correct.

Step-by-step explanation:
the population of a country in 2009 was 642000 and it was increased by 5 % in 2010.
i-Find increase in population.
ii-How much was the population in 2010.
iii-Find percentage of increase over the population of 2009
Answer:
i) 32100 people
ii) 674100
iii) 5%
Step-by-step explanation:
The population in 2009 was : 642,000
The percent increase was by : 5%
This means the population in 2010 will be :
105/100 * 642000 = 674,100
i) Increase in population is ; 674,100 - 642,000 = 32100 people
ii) The population in 2010 was : 674,100
iii) Population of 2009 = 642000
Population of 2010 = 674,100
Increase in population = 674,100 - 642000 = 32100
Percent increase = increase/ original population * 100
Percent of increase = 32100/642000 * 100 = 5%

There is a elephant shaped weather vane at the top of a corn dryer tower that is 45 m high. If the weather vane weighs 190 N, wjat is the potential energy that the wether vane has?
Solution :
Given :
Height of the tower , h = 45 m
Weight of the weather vane, mg = 190 N
So the potential energy possessed by the weather vane is given by
E = m x g x h
where, E is potential energy
m is mass
g is acceleration due to gravity (taken as 10 m/s2)
h is height
Therefore,
E = m x g x h
E = (mg) x h
E = 190 x 45
E = 8550 J

If an odd number is less
than 15, then it is prime.
Answer: That is false
Step-by-step explanation: 9 is odd but not prime
The statement "If an odd number is less than 15, then it is prime" is false because the number 9 is not prime.
What is the number?A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.
It is given that:
If an odd number is less than 15, then it is prime.
As we know,
The prime number is the number that has factors only 1 and itself the number.
The odd number is less than 15.
The odd number is less than 15 = {13, 11, 9, 7, 5, 3}
The statement "If an odd number is less than 15, then it is prime" is false
Because the number 9 is not prime.
Thus, the statement "If an odd number is less than 15, then it is prime" is false because the number 9 is not prime.
