Which equation represents the relation that is shown in the graph?
a. y=x+2/7
b. y=x+7/2
c. y=2/7x
d. y=7/2x

D

Step-by-step explanation:

First let's notice a couple things:

So let's go in order of our realizations.

Let's start with figuring out what b is. By simply looking at the graph, we can see that b = 0, because the line starts at (0, 0). Remember that b is when the line crosses the y axis, and our y value at x = 0 is 0.

This crosses out A and B.

Now let's find m, aka the slope. We can figure this out using the slope formula:

Awesome! So we've figured out that m = 7/2. This means our answer has to be D.

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
