Distance Formula | Algebra | Chegg Tutors Distance Formula | Algebra | Chegg Tutors

The distance formula, typically first taught in 8th grade Algebra, can be used to calculate the distance between two points in 2-dimensional space. Once you know the x and y coordinates of each of the two points that you’re calculating for, its easy enough to plug them in to the equation and solve for the distance, d.

The equation:

d = sqrt((x2-x1)^2 + (y2-y1)^2)

In this video, Chegg Physics tutor Shereka B. walks through an example problem where she calculates the distance between two points, (-2,-3) and (-4, 4), to arrive at a solution. Without the equation, it would be too difficult to calculate the distance just by looking at the two points graphed on an x,y plane. But Shereka uses the graph to help visualize the calculation as she walks through the steps to solve using the distance formula.

About Shereka B., Algebra tutor on Chegg Tutors:

Georgia Tech, Class of 2016
Biomedical Engineering major

About me: As a PhD student I have been a teaching assistant for cell and molecular biology classes taught to undergraduate Biomedical Engineering students. A huge component of my graduate coursework has also included “teaching” the material to my classmates as a way to reinforce and ensure that learning occurred so even in my own classes I had to work in groups, give presentations, and show that I know my information.

Subjects tutored: Pre-Algebra, Natural Sciences, Health and Medicine, Basic Science, Biology, SAT II Biology E/M, Chemistry, Trigonometry, GRE, Biochemistry, Calculus, Applied Mathematics, Basic Math, Bioengineering, Geometry, Algebra, and Pre-Calculus
