Step-by-step explanation:
A graphing calculator does this very nicely.
___
If I were graphing by hand, I might divide by 4 and add 7 to get ...
y = 3x +7
Now, you know the slope is 3 and the y-intercept is 7. Another point can be found by going left 1 and down 3 from the y-intercept, or left 2 and down 6 as shown on the attached graph. The line can be drawn through those points.
B = 40.95d + 50.70 .......
I believe that it is 6 and 76/5. As an improper fraction, it would be 106/5.
