Do You Know Linear Equations And Functions? - Quiz

2.

Y=mx+b, What does m represent?
- Intercept
- Slope
- All of the above
- None of the above
Correct Answer

A. Slope

Explanation

The variable "m" in the equation y=mx+b represents the slope. The slope is a measure of how steep a line is and determines the rate of change between the y and x variables. In this equation, "m" is multiplied by the x variable, indicating that it determines the change in y for a given change in x. Therefore, the correct answer is "Slope".

Which of the following is a linear equation?
- 5x = 6 + 3y
- Y = 2x + 1
- Y/2 = 3 − x
- All of the above
Correct Answer

A. All of the above

Explanation

All of the given equations are linear equations. A linear equation is an equation in which the highest power of the variable is 1. In the first equation, 5x = 6 + 3y, both x and y have a power of 1. In the second equation, y = 2x + 1, both x and y have a power of 1. In the third equation, y/2 = 3 - x, both y and x have a power of 1. Therefore, all of the given equations are linear equations.

Find y in the following equation. y/2 = 3
- 6
- 4
- 5
- 12
Correct Answer

A. 6

Explanation

To find y in the equation y/2 = 3, we need to isolate y. To do this, we can multiply both sides of the equation by 2. This cancels out the division by 2 on the left side, leaving us with y = 6. Therefore, the value of y is 6.

5.

Which of the following is a linear equation?
- 3√x − y = 6
- y/2 = 3
- X3/2 = 16
- All of the above
Correct Answer

A. y/2 = 3

Explanation

A linear equation is an equation that can be written in the form y = mx + b, where m and b are constants. In the given options, only the equation y/2 = 3 can be written in this form. Therefore, y/2 = 3 is the only linear equation among the options provided.

Rate this question:
6.

Which of the following is not a linear equation?
- Y − 2 = 3(x + 1)
- Y = 3x − 6
- 5x = 6
- None of the above
Correct Answer

A. None of the above

Explanation

All of the given equations are linear equations. The first equation is in the form of y = mx + b, where m is the slope and b is the y-intercept. The second equation is also in the form of y = mx + b, with a slope of 3 and a y-intercept of -6. The third equation is in the form of ax + b = 0, which can be rearranged to the form of y = mx + b by dividing both sides by 5. Therefore, all of the given equations are linear equations, so the correct answer is "None of the above".

7.

Which of the following is not a linear equation?
- Y2 − 2 = 0
- Y + 2x − 2 = 0
- 5x = 6
- All of the above
Correct Answer

A. Y2 − 2 = 0

Explanation

The equation y2 − 2 = 0 is not a linear equation because it contains a squared term (y2), which makes it a quadratic equation. Linear equations have variables raised to the power of 1 (y, x) and do not include squared terms.

Which of the following is defined as the equation for a straight line?
- Linear Equation
- Coefficient
- Algebra
- None of the above
Correct Answer

A. Linear Equation

Explanation

A linear equation is defined as the equation for a straight line. It is a mathematical equation that represents a straight line on a graph. The equation is in the form of y = mx + b, where m is the slope of the line and b is the y-intercept. This equation is used to describe relationships between variables that show a constant rate of change.

9.

Which of the following is a linear equation?
- Ax + By + C = 0
- X3/2 = 16
- All of the above
- None of the above
Correct Answer

A. Ax + By + C = 0

Explanation

The equation Ax + By + C = 0 is a linear equation because it represents a straight line when graphed. The variables x and y have a power of 1, and there are no other terms or operations that would make the equation non-linear.
