1. The slope intercept form is:

Where
is the slope of the line and
is the intercept with the y-axis.
2. To calculate the slope, you can use the following formula:

Where:

3. So:

4. Now you must find
. Substitute any of the given points into the equation and solve for
:

5. Therefore, the answer is the last option:
I just plugged all three of these equations into a calculator and A and C both equal 0.
Hope this helped.
Answer:
Answer B - y=[x]+7
Step-by-step explanation:
A normal [x] function has a slope of one, a y intercept of 0, and all the other basic values.
7 changes this.
Looking at the graph, we see that the y intercept is now 7.
How can this be? x was added to by 7.
If it was subtracted, it would be -7, not postive 7.
So the answer is y=[x]+7
