Converting Between Forms With Linear Equations

Rewrite in slope intercept form.

• y = − 6 /5 x − 3

• y = − 6/ 5 x + 3

• y = 3/5x + 6

• y = 3/5x - 6

Convert the equation y = -3x + 4 to standard form.

• 3x + y = 4

• y = -4x + 3

• y = 3x + 4

• -3x + y = 4

Write in standard form: 19x = y

y=-3x+1 y=3x+1 y=1/3x+1 y=-1/3x-1

• y=-3x+1

• y=3x+1

• y=1/3x+1

• y=-1/3x-1

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
Then you multiplied by -2
Now what will it look like?

• -2x -2y=10

• -2x+2y=20

• x-2y=20

• -x+2y=10

• y=-4x-4

• y=x+4

• y=-x+4

• y=4x-4
