Question

What is the equation of the line that passes through the point ( − 4 , 8 )and has a slope of − 1/4

Answer 1

y = -1/4x + 7

Explanation:

Plug in the point and slope into y = mx + b, and solve for b:

y = mx + b

8 = -1/4(-4) + b

8 = 1 + b

7 = b

Plug in the slope and b into y = mx + b:

y = mx + b

y = -1/4x + 7

So, the equation of the line is y = -1/4x + 7
