Okay, so the formula to find slope is y=mx+b, so we would start off by writing that. M in the equation represents the slope and b represents the y-intercept.
equation: y= -2/3x+6. you but the coordinates where it is on the slope formula. 8=-2/3(-3)+b and then you solve for b. then you plug b in with the slope formula along with the slope. so it would be y=-2/3x+b
