The coefficient of x is the value for slope in y-intercept form, and the number that we add or subtract is our y-intercept. So in this case, we want to look for a "-2" in front of x and a +4 in the equation.
Answer choice A fulfills those conditions. (I am also assuming that answer choice A should have had an x in it, but you accidentally forgot to type it.)

The answer is D. 1.601 * 10^9
Answer: 1.960
Step-by-step explanation:
The value of z we use to calculate a confidence interval with a (
) confidence level is a two-tailed test value i.e. represented by :-

Given : The level of confidence: 
Then, significance level : 
With the help of standard normal distribution table for z , we have

Hence, the value of z should be used to calculate a confidence interval with a 95% confidence level =1.960
A horizontal line is one for which the value of y is the same for the entire length of the line. Therefore this type of line can be expressed as below:

Where "c" is a constant that changes the position of the line on the coordinate plane. If c is equal to 2, then we have a constant line that crosses the y-axis at the position 2 for example.
