Question

-6x+y= -4?
Which is the solution?

Answer 1

Explanation:

it has infinite solutions.

e.g.,

y=6x-4

x=0,y=-4

x=1,y=2

x=-1,y=-10

x=1/2,y=-1

so solutions are (0,-4),(1,2),(-1,-10),(1/2,1),...

Answer 2

X=0,y=-4

X=1,y=2

X=2,y=8

Explanation:

-6x+y=-4

When x=0

y=?

-6(0)+y=-4

y=-4

When x=1,y=?

-6(1)+y=-4

-6+y=-4

Add 6 to both sides

y=2

When x=2,y=?

-6(2)+y=-4

-12+y=-4

Add 12 to both sides

y=8

Therefore when x=0,y=-4

When x=1,y=2

When x=2,y=8
