In order to find the equation of a line, you would have to use the equation y=mx+b.
First, find the slope:

There is (1,8) and (2, 16) so plug that in 16-8/2-1 = 8. That's your slope! (Or the m)
Next in order to find b, you have to plug in a point:
y=8x+b
Take (1,8) and plug it in for x and y:
8=8(1)+b
b=0
Your y intercept is 0 (which you can also see on the graph)
So your answer is: y=8x
Ronald originally had 160 dollars.
123.45 + 36.55 = 160. That means that he had 160 dollars.
84 divided into sevenths could either be:
84 x (1/7) or simply 84/7
In the end, the answer would be 12.
