Answer:
y = -5(x-1)
Step-by-step explanation:
A y-intercept of 1 means that the point (0,1) falls on the line.
Slope-intercept form is
where m is the slope...
Therefore, the slope-intercept equation is y-1=-5(x-0) or y-1=-5x

Plug in 300 for C(x), to get:
300=

Then subtract to get: 0=

Then use the quadratic formula and plug everything in. Use a calculator to simplify.
You'll get two answers: 29.486 and -0.513.
