Linear Graph Characteristics

What is the defining feature of a linear graph?

• Wavy line

• Dotted line

• Represents a straight line

• Curved line

How many variables are present in a linear equation?

• 3

• 2

• 4

• 1

What is the slope of a horizontal line?

• 45

• 90

• 1

• 0

What is the slope of a vertical line?

• Negative

• Positive

• Zero

What does the y-intercept represent in a linear equation?

• The y-intercept represents the slope of the linear equation.

• The y-intercept represents the maximum value of the linear equation.

• The y-intercept represents the point where the graph of the linear equation intersects the y-axis.

• The y-intercept represents the x-value where the linear equation crosses the x-axis.

How is the slope calculated in a linear graph?

• Slope = (y2 - y1) / (x2 - x1)

• Slope = (y1 + y2) / (x1 + x2)

• Slope = (y2 - y1) * (x2 - x1)

• Slope = (y1 - y2) / (x1 - x2)

What is the general form of a linear equation?

• y = ax + b

• y = mx + b

• y = mx + c

• y = mx - b

What is the relationship between the x and y variables in a linear equation?

• The relationship between x and y variables in a linear equation is determined by the y-intercept only.

• In a linear equation, x and y variables have no specific relationship.

• The relationship between x and y variables in a linear equation is exponential.

• The relationship between x and y variables in a linear equation is defined by a constant rate of change known as the slope.

How does a linear graph appear on a coordinate plane?

• A linear graph appears as a circle on a coordinate plane.

• A linear graph appears as a straight line on a coordinate plane.

• A linear graph appears as a zigzag line on a coordinate plane.

• A linear graph appears as a curved line on a coordinate plane.

What is the significance of the slope in a linear graph?

• The slope in a linear graph represents the color of the line.

• The slope in a linear graph represents the age of the line.

• The slope in a linear graph represents the rate of change or steepness of the line.

• The slope in a linear graph represents the weight of the line.
