'm' represents the slope of the line, indicating how steep the line is.

'b' represents the y-intercept, which is the point where the line crosses the y-axis.

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

If the slope of a line is -2, what does this indicate about the line's direction?

Back

A slope of -2 indicates that the line is decreasing; for every 1 unit increase in x, y decreases by 2 units.

Back

The slope of the line is -4.

Start at the y-intercept (0, -1) and use the slope (2) to find another point: from (0, -1), go up 2 units and right 1 unit to (1, 1).

The y-intercept is 1.

The graph will pass through the origin (0,0) and have a slope of 3, rising steeply.
