Question 862339: Hi, I'm having trouble with this problem:
Write the equation of the line that contains the indicated pair of points. Express the final equation in standard form. (0,0),(-8,3).
I got a slope of 3/-8, then 8y=-3x
Thank you!

Hi

(0,0),

(-8,3)  m = -3/8  good work 

  y = (-3/8)x

 3x + 8y = 0  is Standard Form

The slope is ( change in y ) / ( change in x )
+%28+3+-+0+%29+%2F+%28+-8+-+0+%29+=+-%283%2F8+%29+
--------------------------------
Then you can use the general point-slope formula
+%28+y+-+0+%29+%2F+%28+x+-+0+%29+=+-%283%2F8%29+
+y+=+-%283%2F8%29%2Ax+
This is the slope-intercept form
--------------
You can also put it in the standard form:
+y+=+-%283%2F8%29%2Ax+
+8y+=+-3x+
+3x+%2B+8y+=+0+
