Compare Slope and Y-Intercept

Write the equation in slope-intercept form:
-3y + 5x = 12

• y = -4 + 5x

• y = -4 + 5/3x

• y = 4 - 5/3x

• y = 12 + 5x

A movie rental store charges a $10 membership fee plus $3.50 for each movie rented. what are the slope and y-intercept that represent this situation?

• slope = 3.50, y-intercept = -10

• slope = -10, y-intercept = 3.50

• slope = 3.50, y-intercept = 10

• slope = 6, y-intercept = 3.50

Determine the slope and y-intercept of the following equation. 7x - 2y = 10
