What is the equation of the line that passes through the points (3,-2) and (-1,2) a) y=-x+1 b) y=-2x-2 c) y=-2x+4 d) y=-x+4 is it a, b,c, or d

A. y = -x + 1

Step-by-step explanation:

First find the slope of the two lines using the slope formula: .

Now use one of the two points; I am going to use (-1, 2).

Substitute the point and slope into the point-slope equation: y - y1 = m(x - x1).

y - (2) = -1(x - (-1))

Simplify.

y - 2 = -1x - 1

Add 2 to both sides and remove the 1 in front of the x. It is not needed.

y = -x + 1
