The slope is Undefined.

Front

Find the slope of the line: (1, 2) and (4, 5)

Back

The slope is 1.

Front

Solve for x: 5x - 14 = 8x + 4

Back

x = -6.

Front

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

Back

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

Front

What does the b represent in the equation y=mx+b?

Back

b represents the y-intercept of the line.

Front

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

Back

It indicates that the line is decreasing from left to right.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is Undefined.
