Step-by-step explanation:
We know that the slope of the line is 1, so we can write it in terms of any two points belonging to the line, as per the difinition of slope:

We can use instead of
any general point (x,y) on the line, and for
the point we are interested in: (11,4)
That way the slope can be written as:

Next we can solve for y if this format is the one your instructor prefers:

1) add 15d to both sides
200<span><80+15d
2) takeaway 80 from both sides
120</span><span><15d
3)divide by 15 to solve the inequality
8</span><span><d</span>
