Find the slope of the following line.

The slope is…

32

Start with the lower point and count how much you rise and run

to get to the other point!

Determine the slope of the line.

Notice the slope is positive AND the line

increases!

What is the slope of a vertical line?

The line doesn’t run!

All vertical lines have an undefined slope.

m number

0undefined

Determine the slope of the line.

The line is decreasing (slope is negative).

What is the slope of a horizontal line?

The line doesn’t rise!

m 0

number0

All horizontal lines have a slope of 0.

rise = 4

run = 5

m= rise

run

m= 4/5

3x + 5y = 10

You try: Put in y intercept form (function form)

5y = -3x + 10

y = -3/5 x + 2

slope= -3/5 y intercept = 2

Skills Check!When you finish turn your paper over

and put it in the corner of your desk. Silent read, work on other homework or practice more problems. No talking.
