The estimated total cost, y, of a child’s toy is partially based on the number of batteries used, x. The cost of one battery is $0.75. The toy itself costs $12. Which equation represents the situation?
y = 12x + 0.75
y = 0.75x + 12
y = 12x – 0.75
y = 0.75x – 12
y = 0.75x + 12

What is the slope and the y-intercept of the line on the graph below?
On a coordinate plane, a line goes through points (0, 1) and (4, 0).
slope = –4, y-intercept = 1
slope = –4, y-intercept = 4
slope = Negative one-fourth, y-intercept = 1
slope = Negative one-fourth, y-intercept = 4
slope = Negative one-fourth, y-intercept = 1
What is the slope of the line in the graph?
On a coordinate plane, a line goes through points (negative 2, negative 1) and (0, 1).
