y=-mx

Front

What does the equation y = -mx represent?

Back

It represents a linear equation where 'm' is the slope of the line, and 'y' is the dependent variable.

Front

What is the slope in the equation y = -mx?

Back

The slope 'm' indicates the steepness and direction of the line. A negative slope means the line descends from left to right.

Front

How do you identify the slope from the equation y = -mx?

Back

The slope 'm' is the coefficient of 'x' in the equation. For example, in y = -2x, the slope is -2.

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on a coordinate plane, written as (x, y).

Front

What does the x-axis represent on a coordinate plane?

Back

The x-axis is the horizontal number line on a coordinate plane where the y-coordinate is zero.

Front

What does the y-axis represent on a coordinate plane?

Back

The y-axis is the vertical number line on a coordinate plane where the x-coordinate is zero.

Front

How do you plot the point (-3, -2) on a coordinate plane?

Back

Start at the origin (0,0), move left 3 units (x = -3), then down 2 units (y = -2).

Front

What are the coordinates of Point C if it is located 4 units left and 2 units down from the origin?

Back

The coordinates of Point C are (-4, -2).

Front

What is the formula to calculate the slope between two points (x1, y1) and (x2, y2)?

Back

The slope m is calculated as m = (y2 - y1) / (x2 - x1).

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that the line rises from left to right.
