Step-by-step explanation:
The points on a horizontal line will always have the same y coordinate.
Since the point (-8, -7) is on this horizontal line, the y coordinate is -7.
So the equation of the horizontal line is y = -7.
Radius on a coordinated plane
In order to find the value of N the below mentioned steps must be followed to make the answer more accurate.
<h3>What is the procedure to find the value of N?</h3>
To find N, you must first determine the overall population size from which a sample is collected. N represents the population's overall size, or the number of people.
For example, if you are conducting a research of voter opinions in a certain state, the value of N would be the entire number of registered voters in that state. The figure of N would be the total number of people who have received treatment with the medicine if you were researching the efficacy of a novel drug.
To calculate the size of the sample required to adequately reflect the population, statistical computations frequently employ the value of N.

<span>So we want to know the new coordinates for the vertex A'(x,y) if we know that the vertex A is at A(-1,2) and vertex B is at B(1,5) and that the triangle ABC is translated 6 units up and 3 units left. So the method is simply to add units 6 to x and 3 to y of A to get A'. Going left means we need to go to negative x direction and going up means we need to go to positive y direction. So: A'(-1-3,2+6) and that is: A'(-4,8). </span>
