If two quantities are proportional, which must be true of a graph showing the relationship between them? Select all that apply.
A The graph is a curve.
B The points on the graph are connected.
The graph increases from left to right.
D The points of the graph form a straight line.
E The points of the graph must include the origin
The points must all form equivalent ratios.

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct

you could deduce the conclusion directly using the facts pertaining to the specific situation.
