Y-Intercept is the starting point

Always start on Y-Axis!

y=mx+b

b is the y-intercept

y=2x+3

so 3 is the y-intercept

Multiple Choice

 $y=3x-4$ 

what is the y-intercept? 

• 3

• -3

• 4

• -4

So the y-intercept

is -1

Multiple Choice

What is the y-intercept?

• 4

• -4

• 0

• 1

Slope is how much we move.

y=mx+b

m is the slope.

y=5x+2

so 5 is the slope

Multiple Choice

 $y=3x+5$  

• 3

• -3

• 5

• -5

So the slope is
2 up 5 right

 $\frac{2}{5}$ is the slope 

Multiple Choice

What is the slope?

• $\frac{3}{4}$

• $\frac{4}{3}$

• $-\frac{3}{4}$

What is slope intercept form?

So y-int is 2
moves down 1 right 3

So answer is B

Multiple Choice

What is the equation of the line?

• A

• B

• C

• D
