Answer:
y = 45x + 25
Step-by-step explanation:
Slope-intercept equation/form:
y = mx + b
________________________
x is the amount of classes that Toshelle will take and each class costs $45.
So, you multiply them by one another to get:
45x
_________________________
Additionally, there is a one-time payment of $25.
So, you add 25 to the cost to get:
+25
__________________________
y is the total amount of money Toshelle has to pay.
Therefore, you place 45x and +25 into a slope-intecept equation/form to get:
y = 45x + 25
