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

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

$$y=-4\left(-2\right)+9$$  

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

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

$$5=-4x+9$$  

What will be the first step to solve this equation?

$$5=-4x+9$$  

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

$$5=-4x+9$$  

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

$$5=-4x+9$$  

$$-4=-4x$$  

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

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

$$y=6x-9$$  

For the second part (Find x when y = -63), which of the following will be the correct equation to start solving the problem?

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

$$-63=6x-9$$  

What will be the first step to solve this equation?

$$-63=6x-9$$  

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

$$-63=6x-9$$  

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

$$-63=6x-9$$  

$$-54=6x$$
