F(2)=-2 and f(1)=1 write a linear function

Step-by-step explanation:

We can use the form to find the linear function.

From , we can write:

From , we can write:

To find for , we can substract the second equation from the first:

To find for , we can use substitution:

∴ is the linear function.

Hope this helps :)

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
