What is an equation for the line with slope 2/3 and 7-intercept 9? 30 points to whoever answers this correctly and gets brainlie

Annette [7]

The equation of the line is y = $\frac{2}{3}$ x + 9

Step-by-step explanation:

The equation of a line in slope-intercept form is y = m x + b, where

m is the slope of the line
b is the y-intercept ⇒ the value of y when x = 0

∵ The line has a slope $\frac{2}{3}$

∴ m = $\frac{2}{3}$

∵ The y-intercept is 9

∴ b = 9

- Substitute the values of m and b in the form of the equation below

∵ y = m x + b

∴ y = $\frac{2}{3}$ x + 9

The equation of the line is y = $\frac{2}{3}$ x + 9

{0, 11, 22, 33, 44, 55, 66, 77, 88, 99, 110}

Step-by-step explanation:

<u>The relationship is:</u>

y = 11x

y - is the money received for the coupons, x- is the number of coupons

<u>x is the domain and it includes whole numbers from 0 to 11:</u>

x = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

<u>y is the range and it includes the set of numbers:</u>

y = {0, 11, 22, 33, 44, 55, 66, 77, 88, 99, 110}
