7x+2y=-8
8y=4x
is this equation a dependent, inconsistent, or independent system.?
------------------
Put both equations into the slope-intercept form so you can see the slope of each.
y = (-7/2)x - 4
y = (1/2)x
-------------------
The slopes are different so the lines must intersect in one point.
Therefore the system is independent.
