Evaluate the function

 $g\left(x\right)=-3x-4$ 

Find  $g\left(-6\right)$   

WRITE AN EQUATION
You bought a $5 magazine and four
erasers. You spent a total of $25. How
much did each eraser cost?

• 5+x=25
• 5+4x=25
• 5x=25
• 23-5=4x

Which equation in standard form has a graph that passes through the point  $\left(-4,\ 2\right)$   and has a slope of  $\frac{9}{2}$  ? 

•  $9x-2y=36$  

•  $9x-2y=26$  

•  $9x-2y=-40$  

•  $9x-2y=-10$  

 $\left(6,\ -6\right)$   $\left(8,\ 8\right)$  

What is the equation in slope-intercept form that contains the points

•  $y=-\frac{1}{7}x-48$  

•  $7x-y=48$  

•  $y=7x-48$  

•  $y-8=7\left(x-8\right)$  

If  $g\left(x\right)=\frac{4}{3}x+\frac{7}{9}$  what is the value of  $g\left(3\right)$  ?

•  $g\left(3\right)=\frac{43}{9}$  

•  $g\left(3\right)=\frac{19}{9}$  

•  $g\left(3\right)=\frac{47}{9}$  

•  $g\left(3\right)=\frac{34}{9}$
