Write linear equation m=3 and runs through the point (9,2)

To solve the question, use the equation y=mx+b. Since you already know the slope (m), all you need is to find the b. Plug in the x and y from the point (9,2) and m:

2=3(9)+b
2=27+b (subtract 27 on both sides)
b=-25

The equation is y=3x-25

than do 23.50 times 18 and then divide your answer by 100 than you will get x.
