Question 754621: x/5 - y/8 =1
Graph the equation using x and y intercepts. I understand the x and y intercepts but am having a hard time getting to that point. Any help would be appreciated! Thanks Lexi

You can put this solution on YOUR website!
The x-intercept is at ( x,0 )
The y-intercept is at ( 0,y )
+x%2F5+-+y%2F8+=+1+
Multiply both sides by +40+
+8x+-+5y+=+40+
----------------
x-intercept:
+8x+-+5%2A0+=+40+
+8x+=+40+
+x+=+5+
( 5,0 )
----------
y-intercept:
+8%2A0+-+5y+=+40+
+-5y+=+40+
+y+=+40+%2F+%28-5%29+
+y+=+-8+
( 0,-8 )
----------
Here's the plot:
+graph%28+400%2C+400%2C+-10%2C+10%2C+-10%2C+10%2C+%288%2F5%29%2Ax+-+8+%29+
