Converting Standard Form

$$ax\ +\ by\ =\ c$$  

$$y\ =\ mx\ +\ b$$  

$$a^2\ +\ b^2\ =\ c^2$$  

$$y\ =\ ab^x$$  

$$ax\ +\ by\ =\ c$$  

$$y\ =\ mx\ +\ b$$  

$$a^2\ +\ b^2\ =\ c^2$$  

$$y\ =\ ab^x$$  

You cannot graph standard form equations.

You cannot plug in x and y values.

Desmos will not allow you to type standard form equations.

You have to solve for the x value.

Subtract 1

Add -1

Multiply 1

Divide by -1

No. You do not multiply 5 on both sides. You divide the 5.

Yes.

No. You do not multiply 5 on both sides. You subtract the 5.

No. You do not multiply 5 on both sides. You add the 5.

Convert the equation to slope intercept form

Nothing.

Delete the equal sign and -2.

Add y =

points

a graph

a table

a table, graph, or points.

Nothing. This is the correct answer.

Wayne did not divide by -2

Wayne should not have subtracted 3x. He should have added 3x.

Wayne should have a -2 not a +2.

The error is in step 1. You should not add 8x, you should multiply 8x.

The error is in step 2. You should not divide by 3. You should divide by -3.

The error is in step one. You should subtract 8x, not add.

There is no error.

x + 20 = 5y

$$y\ =-\frac{1}{5}x\ +\ 4_{ }$$  

y = 5x + 100

$$y\ =-\frac{1}{5}x+15$$
