4 Linear Equations in Two Variables A linear equation in two variables is an equation that can be written in the standard form Ax + By = C, where A, B, and C are constants (A and B not both 0), and x and y are variables. A solution of an equation in two variables ...
Match linear functions with their graphs Find the x-intercept of a function given its equation Find the equations of vertical and horizontal lines We previously wrote the equation for a linear function from a graph. Now we can extend what we know about graphing linear functions to analyze graphs...

Skill in coördinate geometry consists in recognizing this relationship between equations and their graphs. Hence the student should know that the graph of any first degree polynomial y =ax + b is a straight line, and, conversely, any straight line has for its equation, y =ax + b....
both equations are satisfied by the solutionx= 2,y= 3. The point (2, 3) is the intersection of the straight lines represented by the two equations.See alsoCramer’s rule. Alinear differential equationis of first degree with respect to the dependent variable (or variables) and its (or t...

Now you can graph both equations using their slopes and intercepts on the same set of axes, as seen in the figure below. Note how the graphs share one point in common. This is their point of intersection, a point that lies on both of the lines. In the next section we will verify ...
