Question

If a line goes through the point (2, 7) and has a slope of -2, what is the equation of the line?

Answer 1

y = -2x + 11

Explanation:

Slope point equation:

y - y1 = m(x -x1)

y1 = 7 ; x1 = 7 , m = -2

y - 7 = -2(x - 2)

y - 7 = -2x -2*(-2)

y -7 = -2x + 4

y = -2x + 4 + 7

y = -2x + 11
