Slope is a measure of Steepness.

Types of Slope Zero Negative Positive Undefined or No Slope

Slope is sometimes referred to as the “rate of change” between 2 points.

used to represent slope. The letter “m” is used to represent slope.

If given 2 points on a line, you may find the slope using the Formula….

Find the slope of the line through the points (3,7) and (5, 19).

(3, 4) and (-6, -2)

What if the numerator is 0? denominator is 0?

If given an equation of a line, there are 2 ways to find the slope and y-intercept.

One method is to write the equation in slope-intercept form, which is y = mx + b. slope y-intercept

Find the slope and y-intercept of the following equations.

m = _____________ b = ____________

First, solve the equation for y. 3x + 5y = 10    

8x + 11y = 7 Find the slope and y-intercept of the following equations. 8x + 11y = 7    

-6x = 2y + 14

If given the graph of a line, find the slope by using the “triangle” method to find the rise over run.

Positive Sloping Line run = 5 rise = 4
