You are watching: An equation whose graph is a line
2 direct Equation: one equation who graph forms a line. Is linear. Is not. In straight equations, every variables are taken come the first power. Linear method of a line. For this reason a linear equation is the equation that a line. Why?
3 expect you were asked to graph the solution set of the direct equation, You might start by developing a table the values.
4 Choose any kind of number to usage as x or y...
5 ... And substitute the number for the variable. Then calculation to find,
6 Continue, until you have actually 3 set of x and y values.
8 v your table completed for 3 sets the values, girlfriend are ready to graph the line.
9 once x is 0, y is 3, for this reason plot the point, (0, 3).
10 and when x is 3, y is 0, so plot the point, (3, 0).
11 and finally, when x is -3, y is 6, for this reason plot the point, (-3, 6).
12 If the three points carry out not heat up, you need to discover your mistake. If they do line up, you just need to affix the dots.
13 This is the graph of the straight equation,
14 create a table of values for every equation, and graph the on net paper: 1. 2. 3.
