Question

Question 1: The cost of joining a gym is $195 plus $50 per month. Rewrite the equation to express cost as a function of time, identify the slope and the y-intercept.

Answer 1

Y = mx + b.

m = Slope = 50.
x = Time in months.
b = y-Int. = 195.
b = y-Intercept = 195
Y = Total cost.

Eq: Y = 50x + 195.
