Find the equation for a line that passes through the point (4,8) and intercepts the x axis at -12. Make a sketch of its graph and label it "Line L". Be sure to label the increments on the x and y axis of your graph. Create and write down an equation for a line parallel to Line L. Graph this parallel line. Create and write down an equation for a line perpendicular to Line L. Graph this perpendicular line.

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

-1
