Question

Write the equation of the line that passes through (3,-2) and has a slope of 4 in point-slope form.

Answer 1

Point-slope form is:

y-y1=m(x-x1) where m=slope and (x1,y1) is any point on that line.

We are given m=4 and (x,y)=(3,-2) so

y+2=4(x-3)

Answer 2

Well first, we have to find the y intercept. So plug in your coordinates.
-2 = 4 (3) + b
Simplify
-2 = 12 + b
now, let's put like terms together.
-14 = b
b= -14
