Step-by-step explanation: Normally you can
look for places where the graphed line crosses the grid. Count the number of vertical squares. This is the numerator. Count the number of squares horizontally. This is the Denominator.
In these examples, the scales on the graphs have different scales on the horizontal and vertical dimensions. So you have to choose numbers from the graph and calculate the rates of change.
There are mnemonic acronyms out there for reminding you how to do this. I think of it simply as using the distributive property. (4x-3)(x+5) = 4x(x+5) -3(x+5) then again = (4x² +20x) + (-3x -15) = 4x² + (20-3)x -15 . . . . . . . combine like terms = 4x² +17x -15
