7. What is the equation in point-slope form of the line passing through (-1, 3) and (1,7)? Oy - 7 = 4(x - 1)
Oy - 7=2(x - 1)
Oy -3=2(x - 1)
Oy - 3 = 4(x + 1)​

step-by-step explanation:

a and d

greater than one

step-by-step explanation:

i'm sorry mate, but i am not seeing any figures. i am unable to solve this for you.

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
