We have

3x+7=11x+15

We subtract 11x on both sides and 7 on both sides

3x-11x+7-7=11x-11x+15-7

we sum like terms

\begin{gathered} 3x-11x=15-7 \\ -8x=8 \\  \end{gathered}

Then we isolate the x

x=-\frac{8}{8}=-1

ANSWER

x=-1

The equation only have one solution

-1 or -x

If you want to find the equation use one of the points you have.

4 = -1(-3) + b

4 = 3 + b (subtract 3 on each side)

1 = b

y = -1x + 1 is the equation
