What is a linear equation?

• An equation that represents a straight line when graphed on a coordinate plane.

• An equation that represents a hyperbola when graphed on a coordinate plane.

• An equation that represents a circle when graphed on a coordinate plane.

• An equation that represents a parabola when graphed on a coordinate plane.

How do you determine the rate of change from a function table?

• Find the difference in the output values and divide it by the difference in the input values.

• Add the output values and divide it by the input values.

• Multiply the output values by the input values.

• Subtract the input values from the output values and divide it by the sum of the input values.

How do you graph a linear equation?

• Connect random points with a zigzag line.

• Plot points and connect them with a curved line.

• Plot points and connect them with a straight line.

• Use a compass to draw a curved line.

What is the y-intercept of a linear equation?

• The y-intercept is the point where the line crosses the x-axis.

• The y-intercept is the point where the line crosses the y-axis.

• The y-intercept is the slope of the line.

• The y-intercept is the point where the line intersects the y-axis at a 45-degree angle.
