*you get 16 points* answer i am failing picture above

7.  f(2) =-2

Step-by-step explanation:

7.f(2) means the value of the function at x =2   or the y value at x=2

f(2) =-2

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
