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.  

Oct 8­1:11 PM

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

  

The steepness is called Slope.

Oct 8­1:21 PM

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.

Oct 8­3:24 PM

Slope of line passing through two points (x1, y1) and (x2, y2) is 

1) Find the slope of the line containing the points (­1, ­2) and (2, 5).  Graph the line.

Oct 8­3:29 PM

2) Find the slope of the line containing the points (1, ­1) and (­2, 4).  Graph the line.

3) Find the slope of the line containing the points (3, 4) and (0, 2).  Graph the line.

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

Oct 8­3:35 PM

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

7) ­4x + 2y = 7
