Question 116445: I am so lost on this part of geometry could someone please explain in simplest

form of how to graph y=5x-7
y-5x=8
and show me exactly how you got this answer.
Thank you greatly. chris

You can put this solution on YOUR website!
Y=5X-7 (RED LINE)
THIS LINE HAS A SLOPE OF 5 & A Y INTERCEPT OF (0,-7)
TO FIND ANOTHER POINT SET Y=0 & SOLVE FOR X
0=5X-7
5X=7
X=7/5 WHICH IS THE X INTERCEPT (7/5,0)
----------------------------------------------
Y-5X=8 (GREEN LINE)
Y=5X+8 HERE WE ALSO HAVE A SLOPE OF 5 WITH A Y INTERCEPT OF(0,8)
TO FIND ANOTHER POIT SET Y=O & SOLVE FOR X
0=5X+8
5X=-8
X=-8/5 WHICH IS THE Y INTERCEPT (-8/5,0)
