Slope (Blueprint)

Write an equation

100

m = -4

b= 5

y= -4x + 5

200

m= 1/2 

b= -4/5 

y= 1/2x - 4/5

300

m= -3

b= -5

y= -3x - 5

400

m=1

b=-1

y= x - 1

500

m= 12

b= 4/9

y= 12x + 4/9

General Slope

100

How do we find slope on a graph?

Find rise over run.

400

What is the y-intercept?

The line's starting point or where it goes through the y-axis.

500

What makes a graph proportional?

It goes through the origin.

Find the SlopeSIMPLIFY

100

Rise = 3

Run = 3

Slope = 1

200

Rise = 4

Run = 2

Slope = 2

300

Rise = 5

Run = 1

Slope = 5

400

Rise = 10

Run = 4

Slope = 5/2

500

Rise = 4

Run = 6

Slope = 2/3
