Answer: 84%
Step-by-step explanation:
1. You know that the student earned 42 out of 50 points on the last test.
2. Then, to calculate the percent the student earned, you must divide 42 points by 50 points and then you must multiply by 100, as you can see below:
Let's call 
the percent the student earned. Then:
%
Y=mx+b where m=slope=(dy/dx) and b=y-intercept (value of y when x=0)
You have two points...(1,-2),(3,2) so
m=(y2-y1)/(x2-x1)=(2--2)/(3-1)
m=4/2=2 now that you have the slope...
y=2x+b, you can use either point to solve for the y-intercept, I'll use (3,2)
2=2(3)+b
2=6+b
b=-4 so the line is:
y=2x-4
