Question

Which is an equation in Point-Slope form for the given point and slope

Point: ( -3,7); Slope: 4

A. y - 7 = 4 ( x - 3 )

B. y - 7 = 4 ( x + 3 )

C. y + 7 = 4 ( x + 3)

D. y + 7 = 4x - 12

Answer 1

The equation of this line is y - 7 = 4(x + 3)

Explanation:

To find this, start with the base form of point-slope form.

y - y1 = m(x - x1)

Now put the slope in for m and the two coordinates in for (x1, y1).

y - 7 = 4(x + 3)
