Question

A local gym charges a $100 initial membership fee and $19 for each month you stay a member. What are the x and y intercepts?

Answer 1

• y-intercept = 100
• x- intercept = -5.26

Explanation:

• $100 initial membership fee
• $19 monthly fee

Function of relationship:

• y = 19x + 100

y- intercept:

• x =0 ⇒ y = 19*0 + 100 ⇒ y = 100

x - intercept:

• y = 0 ⇒ 0 = 19x + 100 ⇒ 19x = -100 ⇒ x = -100/19 ⇒ x = -5.26
