Which one of these relationships is different than the other three? Write the equation for each line, or find the slope (one of them is different from the other3)

Graph B is different from the others.

Equation for Graph A, C, and D is .

Equation of Graph B is

Step-by-step explanation:

The equation of each line can be written as , where m is the slope.

Using each point given in each graph, we can find m and also an equation for each graph:

✍️Graph A Equation and slope:

Using the point given, (0.8, 4), the slope, m, can be calculated as,

Substitute m = 5 into .

✅Equation for graph A would be .

✍️Graph B Equation and slope:

Using the point given, (10, 55), the slope, m, can be calculated as,

Substitute m = 5.5 into .

❌Equation for graph B would be .

✍️Graph C Equation and slope:

Using the point given, (4, 20), the slope, m, can be calculated as,

Substitute m = 5 into .

✅Equation for graph C would be .

✍️Graph D Equation and slope:

Using the point given, (10, 50), the slope, m, can be calculated as,

Substitute m = 5 into .

✅Equation for graph D would be .

Equation for Graph A, C, and D is .

Equation of Graph B is

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
