When you write an equation in the form

The slope is
and the y-intercept is 
So, in the new line

the slope is 2 and the y-intercept is 3.
Only two points are given. An infinite number of functions can be written that will have graphs going through those two points. We have to assume the only one you're interested in is the linear function.
You can use the 2-point form of the equation for a line to find the function, then use that to fill in the table.

Using this rule Output = Input -2, we can fill in the function table.
Step-by-step explanation:
For SAS, you need two sides to be in proportion and the included angles to be congruent.
A) included angle between XY and YZ is Y, so wrong
B) included angle between UV and WV is V, so correct.
C) this ratio is just wrong.
D) included angle between XZ and ZY is Z, and the ratios check out, so correct.
Answer: 3
