Slope Review
Review of slope from equations, zero slope, undefined slope, and parallel/perpendicular slopes.
2
Slope from slope-intercept form
If the equation is in slope-intercept form (solved for y), then the slope is the number IN FRONT OF the x. NOT the x.
Example: y = mx + b, m is the slope. NOT mx.
mx + b = y, m is still the slope.

Slope from any equation
To find the slope from any equation, solve for y first to put the equation into slope-intercept form. THEN look at the slope.

Zero Slope
Since the slope is the number in front of x, the equation for ZERO slope looks like this: y=0x+b.
However, since any number (in this case, "x") times 0 equals 0, the equation ends up looking like this: y=b, where b is the y-intercept.

What is the equation for the line shown in the graph?
13
Undefined Slope
A line with an undefined slope creates a vertical line. All the x-values of a vertical line are equivalent. Therefore the equation of a vertical line is x = a.

Parallel Slopes
In order for two lines to be parallel, the slopes of their equations must be the same.

Perpendicular Slope
In order for two lines to be perpendicular, the slopes of their equations must be opposite reciprocals of one another.
Perpendicular lines can also be made if one line has a zero slope and the other has an undefined slope.
