The formula for a line on a graph is y=mx+b , where the "+b" is the y intercept. Knowing this, what do you think the answer is? @Ashleyrh1999

This is the basic "blueprint" of the equation: $y=mx+b$ The $$\cal\small{b}$$ is where the y intercept goes through the line. |dw:1421950451423:dw| Since it crossed at the 4, its intercept is 4. For your question, it crosses at the 7, so it would have to be: $y=mx+7$
