What is the equation in slope-intercept form of the line that passes through the points (−4, 2) and (12, 6)?
y = 0.25x + 3
y = 0.25x − 4.5
y = 4x + 18
y = 4x − 42
The graph of a linear function is shown on the grid.

The table shows the amount of pet food in cups remaining in an automatic feeder as a function of the number of meals the feeder has dispensed.
Based on the table, which function models this situation?
f(n) = −3n + 24
f(n) = −1/3n + 16
f(n) = −3n + 64
f(n) = −1/3n + 8
What is the equation in slope-intercept form of the line that passes through the point (5, 0) and is parallel to the line represented by y = 1.2x + 3.8?
y = 1.2x − 6
y = −1.2x + 6
y = 1.2x + 5
y = −1.2x − 5
What are the equation and slope of the line shown on the grid?
y = 6, Slope is -1/6
x = 6, Slope is zero
y = 6, Slope is 6
