Answer:

7.) m = 1/3 ; b = -2.5

8.) m = 2 ; b = 2

Step-by-step explanation:

For m, either do the rise over run method or use 2 points and do (y2-y1)/(x2-x1).

For b, just look at the y-intercept/where it crosses the y axis

I believe those are the right answers but not too sure because the numbers on the graph are a bit blurry so i just assumed it counted by ones.

Answer:

$(40-2)^2$

Step-by-step explanation:

Given: $(38)^2$

To find: the correct option

Solution:

A binomial polynomial is a polynomial consisting of two terms.

A trinomial polynomial is a polynomial consisting of three terms.

On multiplying a binomial $(x-y)$ to itself, a perfect square trinomial $(x-y)^2$ is obtained.

Here, $38=40-2$

So, $(38)^2=(38)(38)=(40-2)(40-2)=(40-2)^2$

Here, $(40-2)$ is a binomial and it is multiplied to $(40-2)$ to get a perfect square trinomial $(40-2)^2$
