Question

when you babysit for 3 hours you are paid $34. When you babysit for 8 hours, you are paid $74 what is the slope of this equation

Answer 1

To calculate the slope (m), we can use the following formula:

$m=\frac{y2-y1}{x2-x1}$

Where (x1,y1) and (x2,y2) are two points of the equation.

We can call y to the payment and x to the hours worked, then, from the given information, we must use the values (3, 34) and (8, 74), by replacing these x and y-values into the above formula, we get:

$m=\frac{74-34}{8-3}=\frac{40}{5}=8$

Then, the slope of this equation equals 8
