Slope of a Line using the Formula

What is the formula to find the slope of a line?

• (y2 - y1) / (x2 - x1)

• (y2 - y1) * (x2 - x1)

• (x2 - x1) / (y2 - y1)

• (y1 - y2) / (x1 - x2)

What are the subtopics related to finding the slope of a line?

• quadratic formula, vertex form, standard form, horizontal and vertical lines

• Pythagorean theorem, trigonometry, calculus, exponential growth

• mean, median, mode, range

• slope formula, slope-intercept form, point-slope form, parallel and perpendicular lines

How do you find the slope of a line given two points?

• slope = (y2 - y1) / (x2 - x1)

• slope = (y1 - y2) / (x1 - x2)

• slope = (x2 - x1) / (y2 - y1)

• slope = (y2 + y1) / (x2 + x1)

If you have two points (x1, y1) and (x2, y2), how do you find the slope of the line passing through them?

• slope = (x2 - x1) / (y2 - y1)

• slope = (y1 - y2) / (x1 - x2)

• slope = (y2 - y1) / (x1 - x2) + 1

• slope = (y2 - y1) / (x2 - x1)
