Hey there! I'm happy to help!
Let's think of this as the equation y=mx+b, where m represents the slope and b equals the y-intercept.
The y-intercept is where the line hits the y-axis. As we can see, it hits it at the y-value of zero. Therefore, our equation is just left as y=mx now because b is 0.
We want to find the slope now. This is known as the rise/run, or the y/x. This is basically saying how far up it goes for every one step to the right. If we go to the x-value of one, we see that the y-value is at a little bit less than one. We want to keep on moving to the right until the y-value is at a nice integer value (number without fractions).
If we keep on moving to the right, we see that at the x-value of 3, the y is at 2. This means that the slope is 2/3. And it makes sense! When we were looking at that value of 1, the y-value was less than one and looked like it was at about 2/3, or 0.666....
This will apply to all points on the line. Our y will always be 2/3 of what x is.
Therefore, the equation is y=2/3x
I hope that this helps! Have a wonderful day!

To find the area of a circle.
We first need the radius.
This is quite simple, the radius is half of the diameter
Knowing the diameter is 14
14 divided by 2 = 7.
Now for a circle here is the equation
A = Area
A = <span>π r ^2
</span>
So we have the radius being 7 but now it needs to be squared.
7 x 7 = 49.
So now our equation is.
A = <span>π 49 ^2 (Keep in mind ^2 is just squared)
</span>
Now this is the answer but we can get more technical by multiplying 49 times <span>π
</span>
Now <span>π equals roughly 3.14
</span>
So we can do 49 x 3.14 cm
Which this equals 153.86
Which rounding to the nearest tenth gets you:
153.9 cm is your area
I really do hope this helps!
