Which of the statements below are true for linear functions? select all that apply.
-the general equation is y=mx+b
-the general equation is y=ax^2+bx+c
-the general equation is y=ab^x
-the graph contains a vertex
-the slope of the graph is constant and can be defined as rise over run

The general equation is y=mx+b

the graph contains a vertex

the slop of the graph is constant and can be defined as rise over run

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

answer is (b.

164 ft2)

a base  

18

b base
