Y = kx
Plug in what we know:
5 = k(8)
5 = 8k
Divide 8 to both sides:
k = 0.625
Plug this back into the equation along with y = 15:
y = kx
15 = 0.625x
Divide 0.625 to both sides:
x = 24
Answer:
there are 2 other forms, point-slope form and slope-intercept form.
Step-by-step explanation:
standard is 
point-slope is 
slope-intercept is 
Given equation is 
Now it says to find f(2)
that simply means plug x=2 because we see that 2 is written in place of x in f(x) and f(2)



Hence final answer is
