Answer:
(6,-9)
Step-by-step explanation:
The easiest way to solve this would be to simply plug the equations into a graphing calculator. Or, algebra also works. Just plug in the x values to see if they yield the same y-value. Upon doing this:
y = -2(6) + 3 = -9
y = -4(6) + 15 = -9
If graphing manually on paper, simply plot the y-intercepts first and give each equation the appropriate slope of -2 or -4.
