Shari takes violin lessons. The equation 288x – 4y = –192 relates y, the total cost of the

lessons, and x, the number of lessons. Shari

incorrectly states that the y-intercept is –192. why did shari think that -192 was the y-intercept?

if is not divided by , then y - intercept becomes .

In such a situation, Shari thought that -192 was the y-intercept.

Step-by-step explanation:

Given:

Solution:

Consider the equation:

To find y-intercept, put

In the second step ,

if is not divided by , then y - intercept becomes .

In such a situation, Shari thought that -192 was the y-intercept.
