On a math quiz, you earn 10 points for each question answered correctly. In the equation below, x represents the number of questions that you answer correctly on this quiz, and y represents the total number of points you score on this quiz. The relationship between these two variables is modeled by the equation y = 10x. What is the independent variable?

The input value or independent variable is number of questions that you answer correctly on this quiz (variable x)

Step-by-step explanation:

Let

x ----> the number of questions that you answer correctly on this quiz

y ----> the total number of points you score on this quiz

In this problem

The output value or dependent variable is the total number of points you score on this quiz (variable y)

The input value or independent variable is number of questions that you answer correctly on this quiz (variable x)

we have

This linear equation represent a proportional relationship between the variables x and y

where

k=10

K is the constant of proportionality or slope of the linear equation

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.
