Front

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

Back

The y-intercept is the point where the line crosses the y-axis, indicating the value of y when x = 0.

Front

How can you determine the slope from two points on a line?

Back

Slope (m) = (y2 - y1) / (x2 - x1) using the coordinates of the two points.
