Putting the equations in slope-intercept form changes the system from

15x + 9y = 36

10x + 6y = 36

to

y = −5
3
x + 4

y = −5
3
x + 6

which statements describe the system of equations? check all that apply.
the lines are parallel.
the lines coincide.
the y-intercepts are equal.
the slopes are equal.
the system has one solution.
