Please see the graph.

Work Step by Step

$y=-2/3x+1$ Let $x=0$ (y-intercept) $y=-2/3x+1$ $y=-2/3*0+1$ $y=0+1$ $y=1$ $(0,1)$ Let $y=0$ (x-intercept) $y=-2/3x+1$ $0=-2/3x+1$ $-1 = -2/3x$ $-1*-3 = -2/3x*-3$ $3 = 6/3x$ $3 = 2x$ $3/2 = 2x/2$ $3/2 = x$ $(3/2, 0)$ Let $x=3$ $y=-2/3x+1$ $y=-2/3*3+1$ $y=-2+1$ $y=-1$ $(3,-1)$
