Questions and Answers

Which of the following is the correct formula to calculate slope?

y = mx + b
y = mx (correct)
y = b
y = x

If two points on a line are given as (x1, y1) and (x2, y2), what is the formula to calculate slope?

(y1 - y2) / (x2 - x1)
(x2 - x1) / (y2 - y1)
(x1 - x2) / (y1 - y2)
(y2 - y1) / (x1 - x2) (correct)

What does 'm' represent in the slope formula?

y-intercept
y-coordinate
slope (correct)
x-intercept

Flashcards

Is y=mx the slope formula?

Incorrect. This is the slope-intercept form representing a linear equation, not the formula to calculate slope.

Slope formula with two points?

The slope between two points (x1, y1) and (x2, y2) is given by the change in y divided by the change in x. The correct formula is (y2 - y1) / (x2 - x1).

What 'm' in slope formula represents?

'm' represents the slope of the line in the equation y = mx + b, where b is the y-intercept.
