• The y-intercept

• The slope

• A point on the line

• The x-coordinate

Which of the following is a correct way to calculate the slope of a line?

• Run over rise

• Change in x divided by change in y

When graphing a linear equation in slope-intercept form, what is the first point you should plot on the coordinate plane?

• The x-intercept

• Any random point

• The y-intercept

• The slope

What type of line is formed when the slope (m) of an equation is zero?

• A vertical line

• A horizontal line

• A diagonal line

• A curved line

What is the slope (m) and y-intercept (b) of the equation y = 3x - 5?

• m = 3, b = 5

• m = -3, b = 5

• m = 3, b = -5

• m = -3, b = -5

Which equation represents a horizontal line that crosses the y-axis at 7?

• x = 7

• y = 7

• y = 7x

• y = 0x - 7

What is the slope-intercept form of the equation 3x + y = 9?

• y = 3x + 9

• y = -3x + 9
