I’m so sorry for this 4 night graph 1.89
I cant really show you how to graph this but i can try to explain it. you would make a 4 quadrant graph and do rise over run.
1)start by making the graph
2) on the line of the graph marked Y is where you would put -4
3) From -4, you would go up (rise) by 2 and go over to the right 1 where you end is the slop
340 = 255
100 = ?
100 times 255 = 25500
25500 divided by 340 is 75
