Algebra Brain Dump

What should I do when i see this?

• Find the shaded region

• Plug in the number 2 for x and y

• Change the top one to y= form and graph to see where they cross

• y-y / x- x

The y-intercept represents.....

• The rate at which y is changing with x

• The ending y-value

• Nothing

• The initial or starting y-value

What should I do when I see these answer choices?

• Leave them like they are

• Just delete the extra number with y

• Get y alone by "cancelling out" or moving the extra numbers from that side

• y - y / x - x

What do you have to do to an equation before you can graph it?

• Make sure all the numbers are positive

• Make sure all the numbers are even

• Make sure y is alone

• Make sure x is alone

For graphs like these, the DOMAIN is always:

• All real numbers greater than or equal to zero

• It depends on where it looks like the lines are

• All real numbers less than or equal to zero

• All real numbers

The word "zeros" means:

• y-intercept

• x-intercepts

• slope

• ones

The word "roots" means:

• y-intercept

• x-intercepts

• slope

• ones

Since "zeros" means x-intercepts, if a question is asking you to find the zeros of an equation, what should you do?

• Use nsolve to find the solution

• Find the slope and work backwards

• Graph the equation so you can SEE the x-intercepts!

• Cross-multiply so you can find the zeros
