In order to graph linear equations by finding intercepts, we must remember what an x and y intercept are. So remember that in an x-intercept itβs the y that equals zero, and for the y-intercept itβs ...
All straight line graphs have an equation that can be written in the form π¦ equals ππ₯ add π, where π, the coefficient of the π₯ term, is the gradient or slope of the line. The constant, π, is ...
When you graph a series of (x,y) coordinates in Microsoft Excel 2010, you can use the program's built-in functions to display the equation for the line created by those data points. This allows you to ...
Higher - The gradients of two perpendicular lines will always multiply to make β1. Make sure you are familiar with finding the equation of a line and calculating gradient to understand equations of ...
