Question

A line that includes the point(-2, 8) has a slope of -6. What is its equation in slope- intercept form?

Answer 1

Slope intercept form is y=mx+b where m is the slope and b is the y intercept. we have the slope is -6 and a point so the beat way to solve is to use point slope form and si.plify this into y intercept forn.

point slope is (y-y1)=m(x-x1) where (x1,y1) is a point o. the line. so we get
(y-8)=-6(x-(-2))
y-8=-6(x+2)
y-8=-6x-12
y=-6x-4
now we have slope intercept form!
