Question

Write an equation of each line.
y
(-2,2)
m=-2

Answer 1

y = -2x+4

Explanation:

Using the slope-intercept form of a line

y = mx+b where m is the slope and b is the y-intercept.

The slope is -2 and a point on the line is (-2,2).

y = -2x+b

Substitute the point into the equation of the line.

2 = -2(2)+b

2 = -4+b

2+4 = -4+4+b

6 = b

The equation of the line is

y = -2x+4
