y=5/6+3
I am not positive on this answer I am sorry if it is wrong
The first question is c i believe, I dont have time to answer the others
Hello!
First of all we find the slope by dividing the difference of the y values by the difference of the x values as seen below.

The slope of our line is 7/2, or 3.5
-------------------------------------------------------------
Now we will put the slope and a point on our line into slope intercept form and solve for b. We will use (-3,11).
11=3.5(-3)+b
11=10.5+b
b=0.5
Our final equation is shown below.
y=3.5x+0.5
I hope this helps!
