Answer:
see graph of y = 5x - 7
Step-by-step explanation:
If graphing is the task, you should rewrite the equation in a y = ax + b form. All straight lines can be described in this form, only the a and b determine which line it is.
Your equation 5x-y=7 has the 5x on the left side, so lets move it to the right. It will get a negative sign (this is the same as subtracting 5x like you did in your picture)
5x - y = 7
-y = 7 - 5x
Now we still have the -y which should be a +y. So we multiply left and right with -1 and get:
y = -7 + 5x
If we swap the -y and 5x (we can, because they are just an addition), we get:
y = 5x - 7
Now the equation is in its "normal" form. It's like the y = ax + b with a and b chosen as a=5 and b=-7.
The normal form is handy because you can immediately see the slope is 5 and the intersection with the y-axis is at y=-7.

Sorry, I only know the answer to B.
Step-by-step explanation:
The answer is 0=0, 2=5, 4=10, 6= 15. Sorry if I am late. But I hope this helps, and Have an amazing day!!
The factor of intensity increase for each whole number increase in the Richter scale is 10. This is because the Richter scale is a logarithmic scale that has a base of 10. As an example, a Richter scale of 1 increased to 2 will have an intensity increase of
10^2 / 10^1 = 10
