Question

Write the point-slope equation of the line through (-2, 1) with a slope of 3.

A. y - 1 = 3(x + 2)
B. y - 2 = 3(x + 1)
C. y + 2 = 3(x - 1)

Answer 1

Do you need help?

Answer 2

y - 1 = 3(x + 2)

Answer 3

1) Use the formula y-y1=m(x-x1) to find your equation
2) Your eqaution would look like y-1=3(x+2)
3) Distribute to get y-1=3x+6
4) Add 1 to both sides to get y=3x+7
5) In your case the answer would be (A)

Hope that helps :D
