Question

What is the equation of the line that passes through the point (-3, 1) and has a
slope of -2?

Answer 1

y = -2x - 5

Explanation:

x1 = -3 , y1 = 1 ; m = -2

point slope form : y - y1 = m(x -x1)

y - 1 = -2(x - [-3])

y - 1 = -2(x + 3)

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

y - 1 = -2x - 6

y = -2x - 6 + 1

y = -2x - 5
