Answer:

Step-by-step explanation:

f(x)-2=(-4-2)/(0-(-2))(x+2)

f(x)-2=-3(x+2)=-3x-6

f(x)=-3x-4

g(x)=3x-4

h(x)=-3x+4

j(x)-10=(22-10)/(6-2)(x-2)

j(x)=3(x-2)+10

or j(x)=3x+4

slope:-

f(x)=(-4-2)/(0-(-2))=-6/2=-3

g(x)=3

h(x)=(1-4)/(1-0)=-3

j(x)=(22-10)/(6-2)=12/4=3

y-intercepts:-

f(x)=-4

g(x)=-4

h(x)=4

j(x)=4

f(x) || h(x)

g(x) || j(x)

so they together represent a parallelogram.

A=12h(b1+b2) solve for b1 please.

Papessa [141]

A = 12h(B1 + B2)
A = 12h(B1) + 12h(B2)
A - 12h(B2) = 12h(B1)

B1 = $\frac{A - 12h(B1)}{12h}$
