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

Back

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

Front

What is the equation of a line with a slope of 1 that passes through the point (2, 3)?

Back

y = 1(x - 2) + 3 or y = x + 1.

Front

How do you convert the equation y = 2x + 3 into slope-intercept form?

Back

It is already in slope-intercept form: y = mx + b.
