Modeling Linear Relationships L1: Graphing Linear Functions Using Slope-Intercept Form

Identify the slope and y-intercept  $y=2+\frac{1}{3}x$  

• Slope =  $-\frac{1}{3}$  , Y-intercept =  $2$  

• Slope =  $\frac{1}{3}$  , Y-intercept =  $-2$  

• Slope =  $2$  , Y-intercept =  $\frac{1}{3}$  

• Slope =  $\frac{1}{3}$ , Y-intercept =  $2$

 Find the slope and y-intercept $12x+3y=24$ 

HINT: Use inverse operations to get y alone...the inverse operations are to subtract the 12x and then divide by 3. Do it on scratch paper.

• y-intercept= -4 , slope= 8

• y-intercept= 8 , slope= -4

• y-intercept=  24  , slope=  $\frac{1}{4}$  

• y-intercept= 24 , slope= -12
