6x - 3y = 12
y intercept at x = 0 is y = 4
x intercept at y = 0 is x = 2
the graph is straight line passing through the two points: (0, 4) and (2, 0)

The graph of an equation has a slope and intercept.[ 13x - 11y - 12 ] is not an equation, and has no graph,until you say that it's equal to something.
1 + 12 = WHAT
There is no equation on the list you're showing that has the same graph as [ 4x + 8y = 12 ].
2x3x2
Let's say you have the quadratic equation x2 - 7x + 12 = 0. Plot the graph of y = x2 - 7x + 12. Where y = 0 (when the graph crosses the x-axis) is a solution to the equation. In this case, it crosses at the points (3,0) & (4,0) so the solutions are x = 3 and x = 4. Now if the graph never touches the x-axis, that means the solutions to the equation are complex numbers.
