Answer:

Step-by-step explanation:
it's not hard
5x+4y=16 y=3/5x-3
y=mx+b <------ slope-intercept form
5x+4y=16
-5x -5x
============
4y=-5x+16
--------------
4
============
y= -5/4+4
Slope is -5/4
y-intercept is 4
y=3/5x-3
slope is 3/5
y intercept is -3
I can't do the graph but I'm sure you can figure it out!
Hope I helped.
Simple, take
868 and round it up to 870
then, take
28 and round it up to 30.
Finally, 870/30
870/30=29
Thus, use the expression 870/30.
