(1) y=-5x+6
3x-4y=-24
rewrite the second equation slope intercept form -4y=-3x-24 or y=(3/4)x+6
The equations are
y=-5x+6
y=(3/4)x+6
They are two straight lines, intersecting at the point (0,6), their equal y-intercept.
The first with slope -5 the second with slope 3/4
 

(2)y=5x-4
10x-2=6
The second line, if it is not mistaken, is really the vertical line 10x=8 or x=8/10
The point for x=8/10 on the first line is y=5(8/10)-4=0.
