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

Write an equation of the line with slope of -4 and point (2, 6).

• y = -4x - 14

• y = -4x + 14

• y = -4x + 6

• y = -4x + 18

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