Slope Intercept and Point Slope

Front

What is the slope in the equation y = 3/7x - 4?

Back

3/7

Front

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

Back

Slope (m) = (y2 - y1) / (x2 - x1)

Front

Write the equation in slope-intercept form (y = mx + b) for a line with slope 9 and y-intercept 2.

Back

y = 9x + 2

Front

What does the 'm' represent in the slope-intercept form of a line?

Back

The slope of the line.

Front

What does the 'b' represent in the slope-intercept form of a line?

Back

The y-intercept of the line.

Front

What is the point-slope form of a line?

Back

y - y1 = m(x - x1) where (x1, y1) is a point on the line.
