quiz:
1: If a flag pole startes at -2 and goes to 4 what is the Y intercept?
2:  12x +30y= 300
3: 30x+60y= 600





answer
1: 2, the slope is -2/4 so that it goes over 2 and up 4 it goes through the 2
2: 2 You will need to get the Y by itself so you would have to subtract the X value from the ending value and then divide that answer by the Y value which will give you your Y. repeat for following.
3: 20
