EXPLANATION
We want to find the equation of the straight line given on the graph.
The general form of a linear equation is given as:
where m = slope; b = y-intercept
To find the slope, we apply the formula for slope:
where (x1, y1) and (x2, y2) are two points on the line
Let us pick (1,2) and (4,4)
Therefore, the slope is:
To find the equation, we now apply the point-slope formula:
Therefore, we have that the equation of the line is:
That is the equation of the line.
Answer:
The ordered pair (-2,5) reflected over the y-axis is (2,5)

Answer and Step-by-step explanation:
given:
Sample size is: n =5000
The sample proportion is: Ṗ = 2739 / 5000 = 54.78%
And the critical value of z for 99% confidence interval is
Z = 2.58
For a 99 % confidence interval we use formula:
Ṗ ± z√(Ṗ(1- Ṗ)/n)
By putting the given values in this formula:
0.54 ± 2.58√(0.54(1-0.54)/5000)
= 0.54 ± 0.018
This gives us upper confidence limit of
0.54 + 0.018 =0.558 = 0.54%
This gives us lower confidence limit of
o.54 – 0.018 = 0.522 = 0.53%
The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other. Once you know the constant of proportionality you can find an equation representing the directly proportional relationship between x and y, namely y=kx, with your specific k.
