Subtract 7x to the other side making the equation, y=-7x+5. Then you fgure which one is your m,and b. using the equation y=mx+b. As you can see m is subsituted with -7 so -7 is slope. (M=slope,rise over run). Then b is also replaced with 5 so your first pairof coordinates are (0,5) Your b is always your y in (x,y) So you plot (0,5) and then from (0,5) you move down the graph 7 times and move one space to the right
