x y
150 300
250 500
360 720
480 960

f(x)=x+150
f(x)=2x
f(x)=x/2
f(x)=2x-100

ccswims · Answer

First you need to find the average rate of change (or slope)

mehek14 · Answer

(y2-y1)/(x2-x1)
substitute the values

ccswims · Answer

so do

960 - 300/480 - 150    then just find your y-axis

mehek14 · Answer

(500-300)/(250-150)
200/100
2

anonymous · Answer

I got f(x)-x/2 is that right ?

mehek14 · Answer

to find the y-intercept use any two points
500=2*250
500 = 500 so no y-intercept
the function is f(x) = 2x
