Question

Which equation below is not an equation that represents the graph shown below?

y + 2 = -3(x - 1)

3x + y =1

y - 1 = -3(x + 2)

y = -3x + 1

Answer 1

The line looks like to be right on the 1 one the y-axis.

Answer 2

\(y - 1 = -3(x + 2) \) is the wrong one

Answer 3

if we multiply out we get
\[y-1=-3x-6\] and then
\[y=-3x-5\] which is incorrect.
all the others are the same, they are all
\[y=-3x+1\]
