Graphing from Slope-Intercept Form

In slope-intercept form, what does the m represent?

( y = mx + b)

• mountains

• Slope

• y-intercept

• mixed up

Answer explanation

We often think of m (slope) telling us how to "move" on the line! Rise over run!

In slope-intercept form, what does the b represent?

( y = mx + b)

• blah blah blah

• bend in the graph

• y-intercept

• slope

Answer explanation

We often think of b (y-intercept) telling us whter the graph "begins" on the y-axis! The value of y when x =0!

What is the slope of the line? (pay attention to the direction of the slope or in what direction you move for the sign of the slope!)

• -2

• 2

• -1

• 1

Why do we want to think of slope as a fraction?

• rise/run or change in y over change in x

• run/rise or change in x over change in y

• Fractions make things better

• Because running makes the problem go faster!

When graphing from slope-intercept form ( y = mx +b), first you graph the ______ value on the ________________.

• m value on the y-axis

• m value on the x-axis

• b value on the y-axis

• b value on the x-axis

When graphing, what do you do after you graph your y-intercept?

• Find slope and move the run(left or right) then move the rise (up or down)

• Find slope and move the rise (up or down) then move the run (left or right)

• Draw a vertical line

• Draw a horizontal line
