Write a linear equation in slope-intercept form using function notation.

• f(x) = 2x + 2

• f(x) = 2x - 2

• f(x) = x + 2

• f(x) = 3x - 2

Is the function represented by the table linear or nonlinear?

• linear

• nonlinear

Which equation represents y as a linear function of x?

• y=8x

• x=5

• y=4x²

• y=x³

Write the equation for the function represented by the table.

Keep the slope the simplified fraction and do not put any spaces in your equation.

What is the equation of the line in slope intercept form given a slope of ⅗ and the point ( 4, 11)

• y = ⅗ x + 7

• y = ⅗ x - 7

• y = ⅗ x + 5

• y = -⅗ x + 11
