Question

Write the following equations in the form y=mx+ b.

1.) x-3y =12
2.)-6x+y=1/3
3.)1/3 x+9y=15

Answer 1

Answer is A

Explanation:

Write the matrix form of the function and solve:

x y 1

1 2 1 = 0

2x + 2y + 5 - 4 - y -5x = 0

-3x + 1 + y = 0

y= 3x + 1

Answer 2

1.)y=-x+3

m=-1 b= 3

Explanation:

x+y=3

-x -x

y=3-x

y=-x+3

m=-1 b= 3

Answer

2.)y=1/3 x -4

m=1/3 b=-4

Explanation:

x-3y=12

-x -x

-3y/-3 = -x + 12/-3

y=1/3 x -4

m=1/3 b=-4
