A line goes through (1, 8) and has a slope of 1

If your looking for the slope Intercept form, the answer is y=1x+7

I hope this answer helps you, and Happy Holidays! :)

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
