Answer:
The question is unclear, however, I can explain what y=7x means.
Step-by-step explanation:
Desmos.com/calculator is a good website for plotting exponential and linear graphs. You should check it out if you haven't already!
This equation means that the value of the variable "y" is equal to 7 times the value of variable "x". On the coordinate plane, the x-intercept and y-intercepts would be at point (0,0). The slope would be 7, according to the graph and the linear equation formula (ie "y=mx+b", y=y value, x=x value, m=slope, b=y-intercept). Is there another part to the question that I can help answer?
The linear equation formula (or whatever is called xD) is y=mx+b. The y-intercept is 0, so the equation will read y=mx+0. The slope is 7, so m=7, and the equation reads y=7x+0. You can eliminate the 0 (because 0=0, 0 is nothing). This is how you would get y=7x by reading a graph.
To find slope, find two solid plotted points on the line of the graph. Count how many units the line ascends, and how many units the point is. This is called rise over run or Rise/Run. This is the standard format to find slope. Divide the numbers, and there is the slope!
If this is not the answer you were looking for, sorry! Not much information was given. :(
