Y=mx+b

Front

What does the equation y=mx+b represent?

Back

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

Front

What is the slope in the equation y=3x+2?

Back

The slope (m) is 3.

Front

What is the y-intercept in the equation y=-4x+1?

Back

The y-intercept (b) is 1.

Front

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

Back

Slope (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.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that the line falls from left to right.

Front

What is the y-intercept of the line represented by the equation y=0.5x-3?

Back

The y-intercept is (0, -3).

Front

In the equation y=mx+b, what does 'b' represent?

Back

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

Front

If the slope of a line is 0, what does that mean?

Back

It means the line is horizontal.

Front

If the slope of a line is undefined, what does that mean?

Back

It means the line is vertical.
