x – 4y = 8B
x – 4y = 2C
4x – y = 8D
4x – y = 222

The ice skating rink charges an hourly fee for skating and $3 to rent skates for the day. Gillian rented skates and skated for 3 hours and was charged $21. Which equation represents the cost, c(x), of ice skating as a function of x, the number of hours of skating?
A
c(x) = 3x + 3B
c(x) = 6x + 3C
c(x) = 7x + 3D
c(x) = 8x + 323
The slope-intercept form of the equation of a line that passes through point (–2, –13) is y = 5x – 3. What is the point-slope form of the equation for this line?
A
y – 13 = 5(x – 2)B
y + 13 = 5(x + 2)C
y – 2 = 5(x – 13)D
y + 2 = 5(x + 13)24
