Slope Intercept Form

​Slope Intercept Form

​LET'S REVIEW

Slope is the STEEPNESS of a line.

​

It helps us make predictions and understand proportional relationships.​

​

• $$\frac{-3}{4}$$  

• $$\frac{-2}{5}$$  

• $$\frac{1}{1}$$  

​NEW INFORMATION

The Y intercept is where a line crosses the Y-AXIS.​

​

​The Y Intercept

​

Multiple Choice

What is the Y-Intercept?

• Where a line crosses the Y AXIS

• Where a line crosses the X AXIS

• The slope of a line

Multiple Choice

What is the y-intercept shown on the graph?

• (0, -2)

• (3, 0)

• (0, 3)

• None of these.

Multiple Choice

_{What is the y-intercept of the line?}

• y = 1/2

• y = 1

• y = -1/2

• y = -1

Multiple Choice

What is the y-intercept?

• -2

• 2

• -4

• 4

​NEW INFORMATION

Proportional relationships are written in this form.

​

m = slope

b = y intercercept

​

By using our knowledge of these concepts, we can write formulas for lines!​

​Example Slope Intercept Form

​In this example the slope of the line is 3/1 and the y-intercept of the line is 2.

​

SO

​

y = 3x +2​
