Linear Equation Formula The linear equation is like any other equation. It is a simple type of equation and is made up of two expressions that are set equal to each other. It contains one variable which can be evaluated by solving the equation. Also, it is equal to the product which is...
Linear graphs are generally straight line graphs represented by the equation y = mx +c where m is the gradient and (0 ; c) is the y-intercept. We can plot a linear graph in the following cases: 1. Where we know two points on the graph. 2. Where we have the...
A linear equation is almost like any other equation, with two expressions set equal to each other. Linear equations have one or two variables. When substituting values for the variables in a true linear equation and graphing the coordinates, all correct points lie on the same line. For a sim...
Linear Equation: We graph a linear equation using the two points that are present on a line. Suppose a linear equation is given; we determine the x and y-intercepts of a line (using the substitution method) to graph it. We draw a straight line that connects two points, and this line ...
Write the final equation in slope-intercept form. Solution First, we calculate the slope using the slope formula and two points. m=−3−40−3=−7−3=73m=−3−40−3=−7−3=73 Next, we use the point-slope formula with the slope of 7373, and either point. Let’s ...
Put the linear equation in slope-intercept formula y = mx + b (which is the form most useful for graphing), by solving for "y." TL;DR (Too Long; Didn't Read) Some ways that a question might give you a slope/point or two points: 2 intercepts, a labeled graph picture showing two...

As an example, an analyst may want to know how the movement of the market affects the price of ExxonMobil (XOM). In this case, the linear equation will have the value of the S&P 500 index as the independent variable, or predictor, and the price of XOM as the dependent variable. ...
