Answer:
C
Explanation:
First find the slope (change in y/ change in x) which is positive 7/9.
Then use y=mx+b and plug in the slope, and one of the given points to solve for b.
5= 7/9*4+b
5=28/9+b
5-28/9=b
45/9-28/9=b
17/9=b
Then with the slope and y intercept(b) you get the equation shown in answer c.
Hope that helps!
