Multiple Representations (Math 8.4B,4C,5i)

Front

What does the letter 'm' represent in the formula y=mx+b?

Back

The letter 'm' represents the slope of the line.

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the rise over run.

Front

What is the y-intercept in the equation y=mx+b?

Back

The y-intercept is the value of y when x=0, represented by the letter 'b'.

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

The slope is calculated using the formula (y2 - y1) / (x2 - x1).

Front

What is a linear equation?

Back

A linear equation is an equation that makes a straight line when graphed, typically in the form y=mx+b.

Front

What does it mean to graph a linear equation?

Back

Graphing a linear equation means plotting points that satisfy the equation on a coordinate plane.

Front

What is the difference between positive and negative slope?

Back

A positive slope rises from left to right, while a negative slope falls from left to right.

Front

What is a coordinate plane?

Back

A coordinate plane is a two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis).

Front

What are the coordinates of the origin in a coordinate plane?

Back

The coordinates of the origin are (0, 0).

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope and will never intersect.
