You are watching: An equation whose graph is a line

1

*

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.

*

7

*

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.
