Multiple Select

Write the following equation in slope intercept form. $$4x-8y=72$$  

• $$y=\frac{1}{2}x-9$$  

• $$y=-4x+72$$  

• $$y=-4x-9$$  

• $$y=4x+9$$  

Multiple Choice

(solve for R)

Watch video for help on example!

Solve the problem on a piece of paper / notebook.

• R = IV

• R = I/V

• R = V/I

• R = V - I

Multiple Choice

ax + c = R

(solve for x)

Watch video for help on example!

Solve the problem on a piece of paper / notebook.

• ax = R + c

• ax = R - c

• x = a(R-c)

• x = (R-c) / a

Multiple Choice
