How do you graph y=8x?

Answer: in the photo
Step-by-step explanation:
To understand how to graph basic linear equations, you'll need to understand the components of the equation. Essentially, 8x will give you the corresponding y value on the graph.
The formula for basic linear equations is y = mx + c, where m is the slope/gradient. Slope is found by rise/run or (y2-y1)/(x2-x1).
For this specific equation, this means that for every 8 units that you take up (rise), you move one step sideways to the right (run).
Since there are no additional components to this equation, the line will pass through the origin (0,0).
Hope this makes sense!

The 1st Quartile that the Box-and-Whisker Plot shows tells us that: <em>A. Three fourths of the fish he caught were larger than 22 pounds.</em>
Recall:
- In a Box-and-Whisker Plot, about 25% of the data will be below the first quartile while 75% will be above the first quartile, that is Three fourths of the data will be above the first quartile and one-fourths will be below the first quartile.
Thus, the given Box-and-Whisker Plot as shown in the diagram below shows that the first quartile is 22 pounds.
Therefore, the 1st Quartile that the Box-and-Whisker Plot shows tells us that: <em>A. Three fourths of the fish he caught were larger than 22 pounds.</em>

Converting the equation into completing the square method we get:
Step-by-step explanation:
we are given quadratic equation:
And we need to convert it into completing the square method.
Completing the square method is of form:
Looking at the given equation
We have a = x
then we have middle term 20x that can be written in form of 2ab So, we have a=x and b=? Multiplying 10 with 2 we get 20 so, we can say that b = 20
So, 20x in form of 2ab can be written as: 2(x)(10)
So, we need to add and subtract (10)^2 on both sides
So, converting the equation into completing the square method we get:
