you have to plug in the x value to discover the y
y= 4.3 x 1
y = 4.3
so, the ordered pair is (1, 4.3)

Using confidence interval concepts, it is found that the interval estimate is (0.274, 0.364), and it means that we are x% sure(considering the confidence level) that the proportion of all voters in the city that plan to vote for the Democratic candidate is between these two values.
<h3>What is a confidence interval?</h3>
It is given by the <u>sample proportion plus/minus the margin of error</u>, and a x% confidence interval means that we are x% sure the population proportion is in the interval.
134 of 420 randomly chosen likely voters indicated that they planned to vote for the Democratic candidate, hence:
p = 134/420 = 0.319
The margin of error for the statistic is 0.045, hence:
0.319 - 0.045 = 0.274
0.319 + 0.045 = 0.364
The interval estimate is (0.274, 0.364), and it means that we are x% sure(considering the confidence level) that the proportion of all voters in the city that plan to vote for the Democratic candidate is between these two values.

17.90/22.95 = x/100
22.95x=1790
1790÷22.95= 77.99
x= 78% (estimated)

The correct answer is D ) (-2, 1) and (3, -2)
In order to find this, we must find the full value of the equation using one of the points and the slope. This will allow us to find the y-intercept. We'll use the (-2, 1) point to start.
y = mx + b
1 = -3/5(-2) + b
1 = 6/5 + b
-1/5 = b
This y-intercept gives us the overall equation of y = -3/5x - 1/5. Now we can try the other point in the equation to see if it works as well.
y = -3/5x - 1/5
-2 = -3/5(3) - 1/5
-2 = -9/5 - 1/5
-2 = -10/5
-2 = -2 (TRUE)
Since this works in the equation, we know that D is the correct answer.
