Question

Write an equation of the line in standard form given the slope through the given point: slope = 4, (-2,-5)

Answer 1

-4x + y = 3.

Explanation:

y - y1 = m(x - x1)

Slope m = 4 and (x1, y1) = (-2, -5) so it is:

y - (-5) = 4(x - (-2))

y + 5 = 4(x + 2)

y = 4x + 8 - 5

y = 4x + 3

Standard form is

-4x + y = 3.
