Question

A line passes through the point (4, -4) and has a slope of -5/4

Write an equation in slope intercept form for this line.​

Answer 1

y= -5/4x + 1

Explanation:

Slope-intercept form: y=mx+b

M is the slope

B is the y-intercept.

The slope is -5/4.

M = -5/4

y = -5/4 + b

We're looking for the y-intercept. Substitute point in.

(4,-4) x= 4 y= -4

-4 = -5/4(4) + b

-4 = -5+b

b= 1

y= -5/4x + 1
