Question

What is the point-slope form of an equation for a line that passes through the point (5, –5) with the slope of 2?

Answer 1

y + 5 = 2(x - 5)

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) = (5, - 5) , thus

y - (- 5) = 2(x - 5) , that is

y + 5 = 2(x - 5)
