Answer

x-intercept: -2 y-intercept: -2

Work Step by Step

(-6, 4) and (3, -5) are given $m = (4--5)/(-6-3)$ $m = 9/-9 = -1$ $y = mx+b $ $4 =-6*-1+b$ $4 = 6 + b $ $4-6 = 6 + b -6$ $-2 = b$ $y=-x -2$ Let x = 0: $y = -1*0 - 2$ $y = -2$ Let y =0: $0 = -x -2$ $0 +2 = -x -2 + 2$ $2 = -x$ $2*-1 = -x * -1$ $-2 = x$
