Question

Examine the following graph of y=−3x+7.

Match each x-coordinate with the corresponding y-coordinate.
x-coordinate=2
x-coordinate=5
x-coordinate=3
x-coordinate=0
-----------------------------------
Answer choices to match with the X coordinates
Y coordinate = -2
Y coordinate = -8
Y coordinate = 7
Y coordinate = 1

Answer 1

y = -3(2)+7

y= -6+7

y= 1

(2,1)

y=-3(5)+7

y= -15+7

y= -8

(5,-8)

y= -3(3)+7

y=-9+7

y=-2

(3,-2)

y=-3(0)+7

y=0+7

y=7

0,7)

Explanation:

substitute the values of x in the equation
