Step-by-step explanation:

$mid \: value \\ = \frac{upper \: limit + lower \: limit}{2} \\ \\ for \: example \\ for \: group \: 10 - 20 \\ mide \: value = \frac{20 + 10}{2} = \frac{30}{2} = 15$

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!
