Graphing Slope-Intercept form

Which value is the slope in the equation:

y= 4x + 2

• 4

• 2

• x

Which value is the y-intercept in the equation:

y= 2x -2

• 2

• -2

• 1

The y intercept is AWESOME! It helps us to know...

• Where our line will end.

• If our line is positive or negative.

• Where to start graphing our line.

Knowing the slope of a line is very helpful! It can tell us if the line is...

• Positive

• Negative

• Will rise to the right.

• Will fall to the right.

This line has a __________ slope.

• Negative

• Positive

• Undefined

• No Slope

This lines has a __________ slope.

• Undefined

• Positive

• Negative

• No Slope

If you have a slope of 1/2 that means you could...

• Go up 1 and right 2 units.

• Go right 1 and up 2 units.

• Go down 1 and left 2 units.

• Go left 2 and down 1.
