Question

Find the equation of the line in slope-intercept form that passes through the point (4, -2) and has slope m = -2. Explain how you arrived at your response.

Answer 1

y + 2 = - 2(x - 4)

Explanation:

The equation of a line in slope- intercept form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = - 2 and (a, b ) = (4, - 2 ) , then

y - (- 2) = - 2(x - 4) , that is

y + 2 = - 2(x - 4)
