What needs to be moved first when converting from Slope Intercept to Standard Form, for y=½x +10?
y=mx+b  ---> Ax+By=C

• subtract 10
• add 10
• subtract ½x
• add ½x

What needs to be moved second when converting from Slope Intercept to Standard Form, for y=½x +10?
y=mx+b  ---> Ax+By=C
The first step was to subtract ½x so now it looks like
-½x +y = 10
Now what?

• multiply by -2
• multiply by 2
• +½
• divide by -2

Write the equation below in standard form
y = 2/3 x +5

• -2/3x+y=5
• -4x+6y=15
• 2x-3y=-15
• -2x+3y=15

Write the equation
 y=2x+1 
in standard form.

• -2x+y=1
• 2x+y=-1
• 2x-y=-1
• 2x+y=-1

What is the formula for standard form?

• y=mx+b
• y-y₁=m(x-x₁)
• Ax+By=C
• rise÷run

Write in standard form.
y = -3x + 5

• y = -3x + 5
• 3x + y = 5
• 3x - y = 5
• -3x + y = -5

Which of the following are written in standard form?

• y=3x-5
• 3x+16=5y
• 2/3 x + 9/13 y = 21
• 5x+7y=-12

Write in standard form.
2x - 2 = 6y

• 2x - 6y = 2
• 2x + 6y = 2
• 2x + 6y = -2
• 2x - 6y = -2

Write in standard form.
y = -3x + 5

• y = -3x + 5
• 3x + y = 5
• 3x - y = 5
• -3x + y = -5
