A line perpendicular to y = -2x + 5 will have an equation in the form of:

y = (1/2)x + b

Since the graph must intersect (-2,9), we plug in this point to solve for b.

9 = (1/2)*(-2) + b

9 = -1 + b

10 = b

So the equation is:

y = (1/2)x + 10

The answer is A.

shutvik [7]

Answer: 95% confidence interval would be (0.449, 0.511)

Step-by-step explanation:

Since we have given that

n = 1022

p = 48% = 0.48

We need to find the 95% confidence interval first.

z = 1.96

Margin of error would be

$z\sqrt{\dfrac{p(1-p)}{n}}\\\\=1.96\times \sqrt{\dfrac{0.48\times 0.52}{1022}}\\\\=0.031$

95% confidence interval would be

$p\pm 0.031\\\\=(0.48-0.031,0.48+0.031)\\\\=(0.449,0.511)$

It means true proportion who felt that economic growth is more important than protecting the environment is within 0.449 and 0.511 using 95% confidence.

-c=p-r
If you were getting the negative C by itself you will want to move the R over on the opposite side. You do that by subtracting are to both sides the hours on the left cancel out leaving you with a negative C on the left side which equals P minus R on the right side
