Identifying Basic Slopes

Slope: the 'steepness' of a line.

​

There are FOUR basic categories for SLOPES

POSITIVE SLOPE

NEGATIVE SLOPE

SLOPE OF ZERO

UNDEFINED SLOPE

Match

Match the graphs with its description of the slope.

Negative Slope

Positive Slope

Slope of Zero

Undefined Slope

• Negative Slope

• Positive Slope

• Slope of Zero

• Undefined Slope

​Slope Intercept Form

​y = mx + b

​slope

​y - intercept

Match

Match the following equations with the description that matches.

• $$y=\frac{1}{2}x-5$$

• $$y=-\frac{1}{2}x+5$$

• $$y=5x+\frac{1}{2}$$

• $$y=-5x-\frac{1}{2}$$

Has a y-intercept of -5

Has a slope of

Has a slope of 5

Has a y-intercept of

• Has a y-intercept of -5

• Has a slope of $$-\frac{1}{2}$$

• Has a slope of 5

• Has a y-intercept of $$-\frac{1}{2}$$

SLOPE: the ratio (fraction) of the rise over the run

POSITIVE Slope Example

​Find the slope of the line

Negative Slope Example

​Find the slope of the line
