Front

What is slope-intercept form?

Back

y = mx + b

Front

Write the equation of the line with slope 3/8 and y-intercept -6. (Do not use spaces.)

Back

y=3/8x-6

Front

Write the equation of the line with slope 3 and y-intercept 5.

Back

y = 3x + 5

Front

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

Back

The slope of the line.

Front

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

Back

The y-intercept of the line.

Front

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

Back

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

Front

If a line has a slope of 0, what does that indicate about the line?

Back

The line is horizontal.

Front

If a line has an undefined slope, what does that indicate about the line?

Back

The line is vertical.
