7, to find the mean add up all the numbers and then subtract by the amount of Humber a you added.
For example, 1,3,8,10 added together is 22. We added four numbers together, so divide by 4. The mean of 1,3,8,10 is 5.5
Constant of proportionality is 4
equation: x/y = 4
explanation:
let's take 20 and 5 for example, if you divide 20 by 5, you will 4 of course. that's the proportionality for the first one. if you continue to divide x value by y value you will get 4. for the last two you would divide 28 by 4 and multiply 8 by 4.

Answer:

Step-by-step explanation:
Given
Perpendicular to 
Pass through 
Required
Determine the line equation
First, we need to determine the slope of 
An equation is of the form:

Where

In this case:

Next, we determine the slope of the second line.
Since both lines are perpendicular, the second line has a slope of:



Since this line passes through (-2,2); The equation is calculated as thus:

Where

This gives:



Add 2 to both sides


Answer:
what does that mean?
