Question

What is the equation in point slope form of the line that passes through the point 

(1, −2)and has a slope of 3?

A) y−1=3(x+2)

B) y+1=3(x−2)

C) y+2=3(x−1)

D) y−2=3(x+1)

Answer 1

Since you already have the slope, you just have to plug in the points in the equation
`y- y_(1) =m(x- x_(1))`

Just plug in the number in for y1 and x1 and you'll get:

`y+2 =3(x-1)`

Which is C!
