Equations of Lines Review

Rewrite
4y = 3 - 4/5x
 in standard form.

• 4x - 20y = 15
• 4x + 4y = 15
• 4x + 20y = 15
• 4x + 4y = 3

Rewrite
y - 2 = 4/3(x - 1) in standard form

• 4x + 3y = -2
• 4x - 3y = -2
• 4x - 3y = 1
• 4x - 3y = -2/3

Write in standard form.
4y - 3 = 6x + 6

• 6x - 4y = -9
• 6x - 4y = 3
• 4y - 6x = -9
• 4x + 4y = 3

Rewrite 
y =10/3x+6  in standard form using integers

• 10x-3y=-18
• -10x+3y=18
• 3x-10y=-18
• -3x+10y=18

y=-4x-4

• 4x+y=-4
• y-4x=4
• y=-4x-4
• y-1=-4(x+2)

y=2/5x+6

• 2x-5y=-30
• -2x+5y=30
• -2/5x+y=6
• 2/5x-y=-6

 Convert to standard form
0=x+2y+3 

• x+2y=-3
• -x-2y=3
• 2x-3y=3
• y=-x/2+3/2

Jimmy purchases movies for $15 each and candy for $3 per bag. His total was $72. Which equation represents his situation?
