Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as x increases, y also increases.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as x increases, y decreases.

Front

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

Back

The y-intercept (b) represents the value of y when x is 0.

Front

In the equation y=0.5x+10, what does the slope represent?

Back

The slope (0.5) represents the per-mile fee for the moving truck.

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

Back

The slope (m) is calculated as m = (y2 - y1) / (x2 - x1).
