Question

Graph the following lines and write the equation in slope-intercept form.

Through the point (−8,1) with a slope of 3.

Answer 1

y=mx+b

3=slope

1=y coordinate

-8=x coordinate

b=y intercept

Substitute m for 3

y=3x+b

Next, substitute the coordinate values

1=3(-8)+b

Solve

1=-24+b

+24 +24

25=b

Now substitute b and m for their respective values

y=3x+25
