y=mx+b

Front

What does the equation y=mx+b represent?

Back

It represents a linear equation where 'm' is the slope and 'b' is the y-intercept.

Front

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

Back

'm' represents the rate of change or slope of the line.

Front

What does 'b' represent in the equation y=mx+b?

Back

'b' represents the y-intercept, the point where the line crosses the y-axis.

Front

How do you calculate the slope (m) using rise and run?

Back

Slope (m) = rise/run.

Front

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

Back

For every 1 unit increase in x, y increases by 2 units.

Front

What is the y-intercept of the line represented by the equation y=3x+5?

Back

The y-intercept is 5.

Front

In the equation y=mx+b, what happens to the line if 'm' is negative?

Back

The line slopes downwards from left to right.

Front

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates a horizontal line.

Front

What does an undefined slope indicate about a line?

Back

An undefined slope indicates a vertical line.

Front

If the equation of a line is y=4x-2, what is the slope?

Back

The slope is 4.
