Multiple Choice

For the first part (Find y when x = -2), which of the following will be the correct equation to start solving the problem?

• $$y=-4\left(-2\right)+9$$  

• $$-2=-4x+9$$  

• $$y=-4\left(2\right)+9$$  

• $$2=-4x+9$$  

Multiple Choice

Is this something you can do with a calculator or do you need to solve the equation like you did in 0.1?

$$y=-4\left(-2\right)+9$$  

• Solve an equation like we learned in 0.1

• Use a calculator or simplify the one side of the equation.

Multiple Choice

For the second part (Find x when y = 5), which of the following will be the correct equation to start solving the problem?

• $$y=-4\left(5\right)+9$$  

• $$5=-4x+9$$  

• $$y=-4\left(-5\right)+9$$  

• $$-5=-4x+9$$  

Multiple Choice

Is this something you can do with a calculator or do you need to solve the equation like you did in 0.1?

$$5=-4x+9$$  

• Solve an equation like we learned in 0.1

• Use a calculator or simplify the one side of the equation.

Multiple Choice

What will be the first step to solve this equation?

$$5=-4x+9$$  

• add 5

• subtract 5

• add 9

• subtract 9

Multiple Choice

After subtracting 9 from each side, what will the new equation be?

$$5=-4x+9$$  

• $$14=4x$$  

• $$14=-4x$$  

• $$-4=-4x$$  

• $$-4\ =\ 4x$$  

Multiple Choice

What's the second and last step to solve the equation?

$$5=-4x+9$$  

$$-4=-4x$$  

• Divide both sides by 4

• Divide both sides by -4

• Multiply both sides by 4

• Multiply both sides by -4

For the first part (Find y when x = -6), which of the following will be the correct equation to start solving the problem?

• $$y=6\left(6\right)-9$$  

• $$y=6\left(-6\right)-9$$  

• $$6=6x-9$$  

• $$-6=6x-9$$  

Multiple Choice

Is this something you can do with a calculator or do you need to solve the equation like you did in 0.1?

$$y=6x-9$$  

• Solve an equation like we learned in 0.1

• Use a calculator or simplify the one side of the equation.

Multiple Choice

After adding 9 to each side, what will the new equation be?

$$-63=6x-9$$  

• $$-72=6x$$  

• $$-54=6x$$  

• $$54=6x$$  

• $$72\ =\ 6x$$  

Multiple Choice

What's the second and last step to solve the equation?

$$-63=6x-9$$  

$$-54=6x$$  

• Divide both sides by 6

• Divide both sides by -6

• Multiply both sides by 6
