Question 44293: what is the equation of the line that contains the points with (x,y) coordinates (-3,7) and (5,-1)?

First, find the slope
m = (y2 - y1) / (x2 - x1)
m = (-1 - 7) / (5 - (-3))
m = -8 / 8
m = -1
Now use the point - slope method
y - y1 = m(x - x1)
y - 7 = (-1)(x + 3)
y - 7 = -x - 3
y = -x + 4
