Explain, in complete sentences, how you would use the graphing method to solve the following system of equations. Part 2: Provide the solution to the system. Part 3: Explain what the solution represents on the graph. 3x – 6y = 12 9x + 2y = –24
well, you graph the functions. the solutions are the points where the 2 functions meet.
solve one equation for y (or x) and then plug it into the second to get the real answer for the other variable. Once you have a real number for x (for example) you can use that value of x in the original equation to find the value of y.
x= -2, y=-3
Thanks
substitution is not graphing .... just a thought
ah, not but part two looks like that is whats needed (albeit poorly worded?)
Part 3: The solution represents the place on the graph (x and y values) where both equations are equal to each other.
