Question

-3x + 6y = 18

-3x = 6y+14

a) What is the slope of the 1st equation?

b) What is the slope of the 2nd equation?

c) Are they parallel, perpendicular, or neither?

Answer 1

#1

• -3x+6y=18
• -x+2y=6
• 2y=x+6
• y=x/2+3

slope=1/2

#2

• -3x=6y+14
• 6y=-3x-14
• y=-1/2x-7/3

slope=-1/2

#3

Neither

Answer 2

Explanation:

-3x + 6y = 18

-3x = 6y+14

a) the slope of the 1st equation = -(-3)/6 = ½

b) the slope of the 1st equation = -3/6 = -½

c) they are niether parallel nor perpendicular
