Now, in this problem, we have to solve the given system of linear equations by graphing.
00:06
And the given system of linear equations we have minus x plus y is equals to 1 and another one we have minus 9x plus 9y is equals to 9.
00:21
Now, we have to graph these equations.
00:24
So, first let me rewrite this equation in this form, x over a plus y over b is equals to 1.
00:32
So, this would be we can write x over minus 1, we can write this way plus y over 1 is equals to 1.
00:40
Right? now, we can divide with 9 both side of this equation here also and here also.
00:47
So, you will get x over minus 1 plus y over 1 is equals to 1.
00:56
Correct? now, you may ask that why we converted this equation in this form because here the for this equation the line cuts the y axis at 1 and it cuts the y axis basically these are the intercepts.
01:13
The line cuts the x axis at minus 1...
