Answer:
y=-1.2x-8.2
Step-by-step explanation:
the equation for the slope is mx+b=y so 6x+5y=11 is the same as 5y=11-6x and that is the same as y=11/5-6/5x. we know the slope is -6/5 and so the y intercept of the line is -7+(-6/5)=-8.2. then the answer is y=-1.2x-8.2

Let d be initial distance the man is from the lamp.
Let x(t) be length of shadow at time t.
The distance traveled is speed*time or 2.8t.
Now set up a proportion between 2 triangles.
One formed by end of shadow and top/bottom of lamp.
Small one formed by end of shadow and top/bottom of man.

Take derivative to find rate that x(t) is increasing.
