Well, 91-70=21. We now know that he score 21 percent better than last test. Then we can make a proportion to find increase as it corresponds to the score on his first math test.

21/70=0.3 or 30%

answer: 30% increase

Can someone please help I’m very confused
Oxana [17]

y + 6 = 4/3(x - 2)

First, distribute the 4/3

y + 6 = 4/3x - 8/3

Subtract 6 from both sides.

y = 4/3x - 26/3

-26/3 is the y-intercept so start the graph at coordinate (0, -26/3)

After you plot the y-intercept, add 4 to they y-coordinate and 3 to the x-coordinate of the y-intercept to get the next point.

0 + 3 = 3

-26/3 + 4 = -14/3

The next point should be at (3, -14/3)

Add as many points as your professor requires.
