F(x)=y
so
f(3)=6 and f(8)=10
the points are
(x,y)
(3,6)
(8,10)

y=mx+b
m=slope
b=yintercept

to find the slope between 2 points, (x1,y1) and (x2,y2)
the slope is (y2-y1)/(x2-x1)
(3,6)
(8,10)
slope=(10-6)/(8-3)=4/5

y=4/5x+b
find b

the equation for a line with slope m and a pointn on it is (x1,y1) is
y-y1=m(x-x1)

a point is (3,6)
y-6=4/5(x-3)
y-6=4/5x-12/5
add 6 or 30/5
y=4/5x+18/5

Please I need your help

Do 5*12 because that's 5*(4+4+4) which the 4s are the base lengths added together. So you have 60 for one part of the figure.

Next, you have 2*4 left to add on to the figure which is 8.

So 60+8=68 is your answer

68 units^2

Hope this helped!

The answer is choice D

Check out the attached image to see the steps on how to get that answer

Notice how I'm marking the rows and columns, and then multiplying the corresponding values together. Also make note of the color-coding.
