Question

What is the point slope form of a line with slope = -2 going through the point (1,-5)? y+5=-2(x-1) y-5=-2(x+1) y=-2x+1 2x+12y=-2

Answer 1

y + 5 = - 2(x - 1)

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) = (1, - 5), thus

y - (- 5) = - 2(x - 1), that is

y + 5 = - 2(x - 1)
