Answer:

Y=1.25x+3.50

Step-by-step explanation:

The problem is linear so it uses y=ax+b form. In this we can set the left group as x and the right group as y. Then use

(y2-y1) / (x2-x1) to find the slope. once the slope is found (1.25) we can find the y intercept by using one of our coordinates with our equation y-ax=b

12.25-1.25*7=b

b=3.5

now we put them all together to make

Y=1.25x+3.50
