To find the slope, we can use the slope formula, i.e., Rise Over Run Formula. The Rise is the change in y, and the Run is the change in x.
Let's use the first Two values for x and y.
The change in y is positive 10, and the change in x is positive 2.
10 ÷ 2 = 5
This means the slope of the equation is 5.
Since the relationship is proportional, there is no y-intercept.
The equation is y = 5x.
