Finding The Equation Of A Line Through 2 Points PART 1 | Graphs | Maths | FuseSchool

In this video we are going to look at how to find the equation of a straight line that passes through two given points (coordinates). You should already know that a straight line follows the y=mx+c format, where 'm' is the gradient and 'c' is the y-intercept. Start by finding the gradient either using gradient = rise / run or gradient = (y2 - y1) / (x2 - x1). This then gives you a value for the gradient 'm' so this can be substituted into the y=mx+c equation. Now the only unknown is the y-intercept 'c' so substitute in either sets of coordinates from the question in place of the 'x' and 'y' to find the unknown 'c'. You would then end up with the equation of the straight line that passes through the 2 points.

Equations are used everywhere: in computers, business, internet searches, medicine to name a few examples. Which is why we study them a lot in Maths.
We have names to describe the different parts: coefficients, variables, constants and exponents. A variable is a symbol for a number we don’t know y

In this video we are going to look at rearranging straight line equations to find the gradient and y-intercept. Straight lines follow the equation y=mx+c, where the m is the gradient and the c is the y-intercept. But straight line equations aren’t always written out in this nice form. Sometimes we h
