Question

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

Answer 1

Slope = m = y1 - y2 / x1 - x2 = 7 --1 / -3 -5 = 8 / -8 = -1
Slope point equation
y - y1 = m(x - x1)
y --1 = -1(x - 5)
y + 1 = -x +5
y = -x + 4

Answer 2

The equation is y = -x + 4 or x + y = 4 or x + y - 4 = 0.
