Answer

x-intercept: 1/3 y-intercept: 1

Work Step by Step

(3, -8) and (-4, 13) are given $m = (13--8)/(-4-3)$ $m = 21/-7$ $m = -3$ $y = mx+b$ $13 = -3*-4 + b$ $13 = 12 + b$ $13-12 = 12 + b -12$ $1 = b$ $y=-3x+1$ Let x = 0 $y = -3*0 + 1$ $y = 0 + 1 $ $y =1 $ Let y = 0 $0 = -3x+1$ $0 + 3x = -3x+1+3x$ $3x = 1$ $3x/3 = 1/3$ $x = 1/3$
