Question 676205: I need help with solving the following system of linear equations by graphing
-10x+2y=14
-5x+y=7
and than both equations in slope intercept form
y=? x+?
y=? x+?
and is it consistent, inconsistent or dependent?
I also have the same question with
3x+3y=15
x+y=-14
thank you and I appreciate it
You can put this solution on YOUR website! -10x + 2y = 14
-5x + y = 7
these are dependent as can be seen by multiplying the second equation by 2
2(-5x+y=7) to get -10x + 2y = 14
...
The lines are the same and every point on the line will be a solution.
...
3x+3y=15
x+y=-14
these are not dependent, as they are different lines, multiply the second equation by -3 and add them
3x + 3y = 15
-3(x+y=-14) to get -3x + -3y = 42
3x + -3x + 3y + -3y = 15 + 42
0 = 57
this an untrue statement, so there is no solution for these lines.
they are inconsistent.
**Notably, these both have the same slope of -1, which means they are parallel and explains why there is no solution.**
