Slope and Slope Intercept

Front

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

Back

m represents the slope of the line.

Front

What is the slope in the equation: y=4x+3?

Back

The slope is 4.

Front

What type of slope does a line with a downward trend have?

Back

A negative slope.

Front

What does the 'b' stand for in y=mx+b?

Back

b represents the y-intercept of the line.

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

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 is the slope-intercept form of a linear equation?

Back

The slope-intercept form is y = mx + b.

Front

If a line has a slope of 2 and passes through the point (1, 3), what is the equation of the line?

Back

The equation is y = 2x + 1.
