The cost of renting a sailboat at a lake is $20 per hour plus $12 for lifejackets. Write an equation in slope-intercept form that can be used to calculate the total amount you would pay for using this sailboat. Please help me. I don't understand.

y = 20x + 12

Step-by-step explanation:

slope intercept form is y = mx + b, where x and y represent the x and y coordinates, m represents the slope, and b represents the y-intercept (the value of y when x = 0). b shifts the entire graph up and down the graph.

for this problem, we can say y is our total cost and x is our total number of hours.

Since the cost of renting the sailboat is $20 per hour, it would be the slope (m).

y = 20x + b

b is the $12 for the life jacks, because it's a one time cost

y = 20x+ 12
