• 48

• 24

• 0

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

• y = 1/2
• y = 1
• y = -1/2
• y = -1

Convert from Standard Form to Slope-Intercept Form.

 $6x-7y=-35$  

•  $y=\frac{7}{6}x-5$  

•  $y=\frac{6}{7}x+5$  

•  $y=\frac{5}{7}x\ -6$  

•  $y=-\frac{6}{7}x\ -5$  

Convert from Standard Form to Slope-Intercept Form.

 $3x-y=-1$  

•  $y=3x+1$  

•  $y=-3x-1$  

•  $y=-3x+1$  

•  $y=3x-1$  

What is the correct equation in 
Slope-Intercept Form?
(y = mx +b)

• y = 3x - 3
• y = 3x - 1
• y = -3x - 3
• y = -3x - 1 

What is the correct equation in
Slope-Intercept Form?
(y = mx +b)

• y = -1/3x + 3
• y = 1/3x - 3
• y = -1/3x - 3
• y = 1/3x + 3
