<h3>
Answer: C. y = 4x-1</h3>
=================================================
Explanation:
Each time x goes up by 1, the y value goes up by 4. The slope must be 4/1 = 4.
You can use the slope formula, picking any two points from the table, to get the same result. Let's say we used the first two rows
m = (y2 - y1)/(x2 - x1)
m = (7-3)/(2-1)
m = 4/1
m = 4
So the answer must be y = 4x-1 as its the only equation with a slope of 4.
To find the y intercept, we plug m = 4 and (x,y) = (1,3) into y = mx+b to solve for b. You can use any (x,y) pair from the table. I picked the first row
y = mx+b
3 = 4(1)+b
3 = 4+b
3-4 = b
-1 = b
b = -1
Since m = 4 and b = -1, we go from y = mx+b to y = 4x+(-1) or y = 4x-1
Answer:
The correct option is mean for shop A because the data distribution is symmetric; median for shop B because the data distribution is not symmetric
Step-by-step explanation:
According to the given data the correct statement is Mean for shop A because the data distribution is symmetric; median for shop B because the data distribution is not symmetric.
Note that the two values of Shop B (10 and 11) are alot lower than the other values.
Thus the correct option is Mean for shop A and Median for shop B...
Let, the number = x
It would be: 13 + 2x + 7 = 6x
2x+20 = 6x
6x-2x = 20
4x = 20
x = 20/4
x = 5
In short, Your Answer would be 5
Hope this helps!
Y - 6 = 4(x - 1)
y - 6 = 4x - 4
y = 4x + 2

Hello from MrBillDoesMath!
Answer:
Cchoice B is the correct answer.
Discussion:
As stated by an earlier respondent, choice B is the correct answer. But why?
From the diagram, point B lies between 0 and 1 which means B is positive
From the diagram, point C lies between -1 and -2 which means C is negative
The quotient of a negative number by a positive number is negative, giving the answer as choice c
