What does the y-intercept represent in a linear function?

Back

The point where the line crosses the y-axis.

If a line has a slope of 2, what does this mean?

Back

For every 1 unit increase in x, y increases by 2 units.

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

Back

Slope (m) = (y2 - y1) / (x2 - x1)
