Vocabulary for Linear Equations

Slope is

• the rate at which the y value of a linear function rises or falls as x increases.

• the point of intersection for a system of equations.

• the value of x at the point where the line crosses the x axis.

• an equation that when graphed will form a straight line.

x - intercept is

• The value of x at the point where the line crosses the x axis.

• The value of x at the point where the line crosses the y axis.

When graphing x and y intercepts what are the coordinates? CHOOSE TWO CORRECT ANSWERS!

• x = 0 is used to find y intercept

• y = 0 is used to find the x intercept

• x = 0 is used to find the x intercept

• y = 0 is is used to find the y intercept

Does this graph represent a proportional relationship? Why?

• No, because it doesn't pass through the origin.

• Yes, because it doesn't pass through the origin.

• Yes, because it intersects the y axis.

• No, because it intersects the x axis.
