Question

Find an equation in slope-intercept form of the line that has slope 2 and passes through point A(-8, 7).
a. y = 23x + 2
c. y = 2x - 23
b. y=-2x+23
d. y = 2x + 23

Answer 1

Answer:

y = 2x+23

Step-by-step explanation:

The slope intercept form is

y= mx+b

where m is the slope and b is the y intercept

y = 2x+b

Substitute the point into the equation

7 = 2(-8) +b

7 = -16+b

Add 16 to each side

7+16 = -16+b+16

23 =b

The equation becomes

y = 2x+23
