Which equation below is not an equation that represents the graph shown below?
line through the points 0 comma 1 and 1 comma negative 2

y + 2 = -3(x - 1)

3x + y =1

y - 1 = -3(x + 2)

y = -3x + 1

No one can help me.:(

anonymous · Answer

ok rearrange all the equations for y. all the others need to look like the last one.

anonymous · Answer

y = -3x + 3 - 2
y = -3x + 1

Thats your 1st equation.

anonymous · Answer

y = 1- 3x

thats your 2nd equation

anonymous · Answer

y = -3(x+2) + 1
y = -3x - 6 + 1
therefore 
y = -3x - 5

thats your 3rd equation.

anonymous · Answer

so now you have the four equations rearranged for y.
