Back

y-intercept

Front

Find the slope of the line that passes through (-2, 8) and (0, 8).

Back

m = 0

Front

Find the slope of the line through each pair of points: (8, 4) and (2, 6).

Back

m = -\frac{1}{3}

Front

What is the slope-intercept form of a linear equation?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you find the slope (m) between two points (x1, y1) and (x2, y2)?

Back

m = \frac{y2 - y1}{x2 - x1}

Front

What does a slope of 0 indicate about a line?

Back

The line is horizontal.

Front

What does a slope of undefined indicate about a line?

Back

The line is vertical.

Front

If the slope of a line is positive, what does that indicate about the line's direction?

Back

The line rises from left to right.

Front

If the slope of a line is negative, what does that indicate about the line's direction?

Back

The line falls from left to right.
