Question 238614: Solve each system of equations by graphing. I dont understand how to switch it into a slope intercept form. I've seen many examples from the book but dont understand how they get the numbers. Will you explain it to me please?
x + 2y = 6
2x + y = 9

I'll get the equations into slope intercept form and let you do the graphing.



Start with the first equation.


Subtract from both sides.


Rearrange the terms.


Divide both sides by to isolate y.


Break up the fraction.


Reduce.


So the equation is now in slope intercept form where the slope is and the y-intercept is note: the y-intercept is the point

-----------------------------



Now move onto the second equation.


Subtract from both sides.


Rearrange the terms.


So the equation is now in slope intercept form where the slope is and the y-intercept is note: the y-intercept is the point
