Final answer:

Ivy earns approximately $8.50 per hour.

Step-by-step explanation:

To find the amount Ivy earns per hour, we can use the formula for a linear equation: y = mx + b, where y is the dependent variable (the amount earned), x is the independent variable (the number of hours), m is the slope, and b is the y-intercept.

From the given points, we can calculate the slope (m) using the formula: m = (y₂ - y₁) / (x₂ - x₁).

Using the points (2, 17) and (5, 42.50), we have m = (42.50 - 17) / (5 - 2) = 25.50 / 3 = 8.50.

So, Ivy earns approximately $8.50 per hour.

Ivy earns 8.5 money per hour for babysitting.

Step-by-step explanation:

The given data is linear and it clearly represents the following information:

(2,17) shows 2 hours = 17 money

(5,42.5) shows 5 hours = 42.5 money

So, to find the money for 1 hour let us assume as "X" money per hour.

Using the rate formula,

Money per Hour= Total money/Total hours

X money/1 hr= 59.5 money/7 hours

X= 8.5 money/hour
