Answer:
y - y1 = m(x - x1)
(x1, y1) = (1, -1) (x2, y2) = (3, 5)
m = [tex]\frac{5 - (-1)}{3 - 1}[/tex]
m = [tex]\frac{5 + 1}{3-1}[/tex]
m = [tex]\frac{6}{2}[/tex] = [tex]\frac{3}{1}[/tex] = 3
m = 3
y - 5 = 3(x - 3)
y - 5 = 3x - 9
y = 3x - 9 + 5
y = 3x - 4
Step-by-step explanation:
In order to use point-slope form to convert to slope-intercept form you have to know one point and the value of the slope. In this case, we know two points, but we don't know the slope. In order to find the slope, you can input the values of the two points into the expression: [tex]\frac{y2 - y1}{x2 - x1}[/tex]
After finding the slope, input the values of one of the points (in this example I used (3,5)) and the slope. After that, multiply the slope by the two terms inside the parentheses. then add 5 to both sides of the equation to isolate y. Now your equation is in slope-intercept form.
I hope this helps :)

-2=-4+x
Answers
Answer:
x=2
Step-by-step explanation:
Add 4 to both sides:
-2=-4+x
-2+4=-4+4+x
2=x
Answer:
[tex]x = 2[/tex]
Step-by-step explanation:
First we must add 4 to both sides.
[tex]-2 = -4 + x[/tex]
+4 +4
-4 + 4 = 0
-2 +4 = 2
Isolating a variable means that it is alone on its side of the eqation.
[tex]2 = x[/tex]
x is now isolated and we also have the solution for it.
[tex]x = 2[/tex]

The Playground Center purchases swing sets for $385.99. It sells the swing sets for $598.99. What is the percent of markup? Round to the nearest percent.
Answers
Answer:
55%
Step-by-step explanation:
$598.99–$385.99
=$213
$213/$385.99 × 100%
=55%
The profit percent is 55.1%.
What is profit Percent?The profit formula aids in determining the gain in any financial transaction as well as the profit made by selling a specific product, which is typically done in a business. When the selling price exceeds the cost price, a profit can be determined. So, the equation to calculate the profit is:
Profit = Selling Price (S.P.) - Cost Price (C.P.)
and, profit percent = (Profit/Cost Price) × 100.
Given:
Playground Center purchases swing sets for $385.99.
Selling price of swing sets = $598.99.
Profit = $598.99–$385.99
Profit = $213
and, profit percent
=profit / CP x 100
= $213/$385.99 × 100%
=0.551 x 100
= 55.1%
hence, the profit percent is 55.1%.

Which group has the largest mean absolute deviation? A) Group 1 B) Group 2 C) Group 3 D) Group 4
Answers
Answer: B) Group 2
Step-by-step explanation:
Given the data:
Group 1 : 18 25 56 42 29 38 54 47 35 30
Group 2 : 23,19,50,49,67,34,30,59,40,33
Group 3 : 19,22,24,40,45,29,33,29,39,59
Group 4 : 21,23,25,40,35,19,70,40,22,23
The mean absolute deviation (MAD) :
Σ(x - m) / n
Where :
m = mean ; n = number of observations
Using calculator to save computation time :
GROUP 1:
m = 37.4 ; n = 10
Mean Absolute deviation = 10
GROUP 2:
m = 40.4 ; n = 10
Mean Absolute deviation = 12.68
GROUP 3:
m = 33.9 ; n = 10
Mean Absolute deviation = 9.48
GROUP 4:
m = 31. 8; n = 10
Mean Absolute deviation = 11.56
9.48 < 10 < 11.56 < 12.68
Group 3 < group 1 < group 4 < group 2
Group 2 has the highest mean absolute deviation with a value of 12.68

Aparabola has the focus at (4,6) and the directrix y = -6. Which equation represents this parabola?
Answers
Answer:
(x - 4)² = 24y
Step-by-step explanation:
In a parabola with focus at (x, y) and directrix at y = k - p, we can write;
Focus: (h, (k + p))
Directrix: y = k - p
We are given focus at (4, 6)
Thus;
h = 4 &
k + p = 6 - - - (1)
Also, directrix at y = -6
Thus;
k - p = -6 - - - (2)
Adding eq(1) and eq(2) together gives us;
2k = 0
k = 0
Thus, p = 6
The equation takes the formula;
(x - h)² = 4p(y - k)
Plugging in the relevant values;
(x - 4)² = 4(6)(y - 0)
(x - 4)² = 24y
Answer:
(x-4)^2=24y
