How do you do this? Please give an example to #1 and explain thoroughly please. I have asked multiple times and gotten answers I
liberstina [14]

Answer:

y=2x

Step-by-step explanation:

y = kx is the format of the graph we are looking for (as told in the instructions) where k is the variable we are supposed to find (like y = x, y=2x, y=3x, etc)

Note that as x increases by 1, y increases by 2. We can see that by writing a table of the points of points that the line given intersects (picture below). We can see that by the values of the x-axis and the y-axis. Why does this happen? This is because y =2x for each value of x. We notice that in our table.

Therefore, the equation is y=2x. I hope this helps! If you still have questions, ask me in the comments!

What is 20-7n=8(n-2). Please show steps.
ipn [44]

First, you need to distribute the right side of the equation : 8n - 2

Now the equation is : 20 - 7n = 8n - 2

Add 2 to both sides : 22 - 7n = 8n

Add 7n to both sides : 22 = 15n

Divide both sides by 15 : ( I had to round this one) 1.5 = n
