Write an equation in slope-intercept form for the situation shown in the image
The slope-intercept form of a line is:
y = mx + b
On Phill's Frozen Yogurt Shop, Phill charges $3.00 for a medium cup of frozen yogurt and $0.50 for each topping.
Let's call x=number of toppings selected for the yogurt.
Since each topping costs $0.50, the x toppings cost 0.50x. The total cost (y) is calculated as:
y = 0.50x + 3
For Frank's Pizzeria, the cost (y) of a medium pizza is
y = 10 + 1.75x
Where x is the number of toppings.
To write this equation in slope-intercept form, we only need to rearrange it as follows:
y = 1.75x + 10
