The only straight line graphs passing through the origin are B and D

Graph in Option D satisfies Proportional Relationship.

What is Proportional Relationship ?

The relationship between two variables such that on increase of one variable the other also increases by some proportion.

It is represented by

y∝ x

y = kx

where k is the proportionality constant

The graph should pass through origin to show a proportional Relation

and should have same proportionality constant through out

Option D satisfies both the condition with k = 0.5.

Therefore Option D is the correct answer.

1.) We can write a equation of a line when we know only the slope and the _____________ of any point of the line.
2.) Given only two points, it is easy to find the equation of the line when you find first the _______________.

Answers

Answer:

1) coordinates

2) slope

Step-by-step explanation:

The equation of a line is given by the two equations:

[tex]y=mx+b[/tex], where m is the slope and b is the y-intercept, or

[tex]y-y_1=m(x-x_1)[/tex], where x₁ and y₁ is the location of any point on the line, and m is the slope.

→ As such, we know that given the slope and the coordinates of any point on a line, we can write the line's equation.

We can also find the slope of a straight line between two points with the following equation:

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex], where m is the slope, x1 and y1 is the location of the first point, and x2 and y2 is the location of the second point. Remember: rise (y) over run (x).

→ So, given only two points, it is easy to find the equation of the line when you first find the slope.

Renee used the values in the table to calculate simple interest.

Principal $750
Interest rate ?
Time 11 years
Interest $412.50

Which interest rate is missing from Renee’s table?

0.05%

0.5%

5%

50%

Answers

Answer:

5% hope its correct

Step-by-step explanation:

The rate of Interest is 55.

What is Simple Interest?

Simple interest is calculated based on a loan's principal or the initial deposit into a savings account. Simple interest doesn't compound, therefore a creditor will only charge interest on the principal sum, and a borrower will never be required to pay further interest on the interest that has already accrued.

Given:

Principal= $750

Time = 11 years

Interest= $412.50

Using Simple Interest

SI= (PRT)/100

412.5 = (750 x R x 11) 100

41250 = 8250R

R= 5%

Hence, the rate of Interest is 55.

Harper measured a line to be 5.4 inches long. If the actual length of the line is 5.3 inches, then what was the percent error of the measurement, to the nearest tenth of a percent?

Answers

The percent error of the measurement is 1.9%.

Given that, Harper measured a line to be 5.4 inches long.

What is percentage?

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

If the actual length of the line is 5.3 inches

So, the difference of length of line = 5.4-5.3

= 0.1

Now, the percent error = Difference in length of line/Actual length × 100

= 0.1/5.3 × 100

= 0.01887 × 100

= 1.9 %

Therefore, the percent error of the measurement is 1.9%.
