Question 243533: Solve the system of the equations by graphing. Then classify the system.
3x-y=24
3x+4y=-6

First, get both equations into y = mx + b format.
.
3x -y = 24
Add y to both sides
3x = 24 + y = y + 24
Subtract 24 from both sides
3x - 24 = y
y = 3x - 24
.
3x + 4y = -6
Subtract 3x from both sides
4y = -6 - 3x = -3x - 6
Divide by 4

The lines intersect, so we know the system of equations have a solution, so they're consistent. That they have only a single solution means they are independent.
