Question 515309
1.)
y = 4x - 7
y = 3x + 2

This ahs one solution. The slopes are different and the y intercepts are not the same. So trhey will intersect


2.)
y = 3x - 6
y = 3x + 1

the slopes of the lines are same and the y intercepts are different. So zero solution. As the lines will never meet.


3.)
-2x + 3y = 2
6y - 4X = 4


When you multiply the first equation by 2 you find that both lines are identical. same slope , same intercept. It means that the lines coincide  and has innumerable solutions
