SOL 8.16b Slopes, Intercepts, and Equations

What is the slope of the table shown?

What is the y-intercept of the table?

Answer explanation

A y-intercept is where the line crosses the y-axis.

Any point on the y-axis has an x-coordinate of 0.

In the table we look to see where x is 0 and the number in the y-column is the y-intercept.

What is the equation of the line shown in the table?

What is the slope of the table?

What is the y-intercept of the table?

Answer explanation

Recall that a y-intercept is where a line goes through the y-axis.

Any point on the y-axis has an x-coordinate of 0.

Look in the table where the x is 0. The number in the y-column is the y-intercept.

What is the equation of the line shown in the table?

Match description with the table, graph or equation that matches.

• positive

• 
• negative

• zero

• 

What is the slope of the graph?

Answer explanation

This is a horizontal line... all horizontal lines have a slope of 0.

Or our change in y is 0 (we don't move up or down).

Our change in x is however many spots you move to the next point.

Then we do change in y over change in x.
