Find the slope of the line through the pair of points. a(2, –3), p(2, 9)

Set:

(x₁ , y₁) = (2, -3)

(x₂ , y₂) = (2, 9)

Note that the equation is:

(y₂ - y₁)/(x₂ - x₁) = slope

Plug in.

(9 - (-3))/(2 - 2) = 12/0

Undefined, which means the line would be vertical.

hope this helps

step-by-step explanation:

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
