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 'b' is the y-intercept.

Front

What is the slope in the equation y=mx?

Back

The slope 'm' indicates the steepness and direction of the line.

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as x increases, y also increases.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as x increases, y decreases.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

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

Back

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

Front

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

Back

The y-intercept 'b' is the point where the line crosses the y-axis.

Front

If the slope of a line is 2, what does this mean?

Back

It means that for every 1 unit increase in x, y increases by 2 units.

Front

What is the slope of the line represented by the equation y=-3x+4?

Back

The slope is -3.
