Subm

What is the point-slope form of the equation for the line with a slope of -2 that passes through the point (4, -6)?

Answer 1

y + 6 = - 2(x - 4)

Explanation:

The equation of a line in point- slope 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, - 6) , thus

y - (- 6) = - 2(x - 4) , that is

y + 6 = - 2(x - 4)
