For this case we have the following equation:

We must clear the value of the variable "x" as a function of r, s and t:
If we multiply by "r" on both sides of the equation we have:

If we subtract "t" on both sides of the equation we have:

If we divide by "2" on both sides of the equation we have:

Thus, the value of the variable "x" is:

Answer:

It’s the last answer because the slope equals 1 which basically equals just x. And the y intercept is -5
It would be k because anytime a line is dotted it uses the symbol < or >
