What is the x-intercept of the line?

Back

The x-intercept is the point where the line crosses the x-axis. For the line represented by the equation, the x-intercept is (-1, 0).

Front

Find the slope of the line.

Back

The slope of a line is a measure of its steepness. In this case, the slope is 1/2.

How do you find the x-intercept of a linear equation?

Back

To find the x-intercept, set y = 0 and solve for x.

Front

What does it mean for a line to have a negative slope?

Back

A negative slope indicates that as x increases, y decreases, resulting in a downward slant from left to right.

What is the formula for the slope between two points (x1, y1) and (x2, y2)?

Back

The formula is m = (y2 - y1) / (x2 - x1).
