Algebra I Review of Linear Functions

The graph of the line y = 6 is a line that has the following characteristic

• parallel to the y axis

• parallel to the x axis

• passes through the orgin

• passes through point (0, 3)

What are the intercepts?

• x-intercept (0, 4); y-intercept (0, -2)

• x-intercept (0, -2); y-intercept (4, 0)

• x-intercept (4, 0); y-intercept (0, -2)

• x-intercept (-2, 0); y-intercept (0, 4)

What is the equation for the graph in slope-intercept form?

• -1/2x + y = -2

• 4x - 2y = 8

• y = 1/2x - 2

• y = 2x - 2

What are the intercepts?

• x-intercept: (3, 0); y-intercept: (0, 5)

• x-intercept: (0, 3); y-intercept: (5, 0)

• x-intercept: (0, 5); y-intercept: (3, 0)

• x-intercept: (5, 0); y-intercept: (0, 3)

Which describes a characteristic of a linear function?

• As the x -value increases, the y -value increases or decreases at a variable rate.

• As the x -value increases, the y -value increases or decreases at a constant rate.

• As the x -value increases, the y -value increases or decreases with a constant percentage.

• As the x -value increases, the y -value increases or decreases without a defined pattern.
