What is the equation of the line first written in point slope form and then written in slope intercept form? show how you did it

We have the points (3, 21) and (6, 12).

The slope-intercept form: y = mx + b.

The point-slope form:

Substitute:

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )
