Question

Solve the system 2x - 3y = 0 and x + 4y = -11 by graphing each line.

Answer 1

well both equations are lines so you can easily graph them by plotting some points.
but the best way probably is to see how that equation intersect with the x axis, y axis, and each other lines
*x-intersection (y=0)
for example for 2x-3y=0
plotting y=0 into the equation will give
2x-0=0, which will then prove that x=0
*y-intersection(x=0) the same way with the above
*intersection with each other equation:
basically set them equal to each other.
from the first equation we get 2x=3y -> x=3/2y
plugging this to the second equation will give you the points of intersection, which is supposed to be the solution for your answer
