Chapter 3.4(a) The Slope of a Line
Find the slope of a line give two points on the line and find the slope of a line given the
equation of a line.

We use the rise and run to describe the steepness of a hill, stairway or a roof line.
The steepness is called Slope.

Slope of a line is measured as a ratio of vertical change to horizontal change.
Slope is also considered the rate of change between points.

SlopeIntercept form:
y = mx + bm is the slope and b is the yintercept (0, b).
Find the slope and the yintercept of the following lines.
3) y = 3x 4
4) y = ¼x + 6

If the equation is not in slopeintercept form we can we can rewrite it by solving for y.
Find the slope and yintercept of the lines.
5) 2x 4y = 8
6) 2x 3y = 9
