![]() The number in front of the \(x\) is the gradient of the graph.Īs you move along a line from left to right, you might go up, you might go down or you might not change at all. ![]() If you are a student or teacher, this app is perfect for your needs to check and validate your equations you made for homeworks. The graphs \(y = 2x\) and \(y = 4x\) are shown below: Graph to Equation Graph to Equation is a lightweight handy tool used to generate equations\functions from graph instantly. This is known as the \(y\) -intercept and is represented by the letter \(c\) in \(y = mx + c\). The constant term in the equation (the + 1 or ‒ 2) shows the point where the graph crosses the \(y\) -axis. Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals. Then scroll to the bottom of the page, and hit Create Chart. The graph of \(y = 2x - 2\) crosses the \(y\) -axis at (0, -2). The easiest way to create the chart is just to input your x values into the X Values box below and the corresponding y values into the Y Values box. Make bar charts, histograms, box plots, scatter plots, line graphs, dot plots, and more. ![]() The graph of \(y = 2x + 1\) crosses the \(y\) -axis at (0, 1). Create charts and graphs online with Excel, CSV, or SQL data. It also outputs slope and intercept parameters and displays the line on a graph. The graphs of \(y = 2x + 1\) and \(y = 2x - 2\) are shown below. \(m\) is the gradient, or steepness of the graph, and \(c\) is the \(y\) - intercept, or where the line crosses the \(y\) -axis. 3 Consider the type of graph you want to make. Its a white box in the upper-left side of the window. Its app icon resembles a green box with a white 'X' on it. Any equation that can be rearranged into the form \(y = mx + c\), will have a straight line graph. This wikiHow tutorial will walk you through making a graph in Excel.
