Question 151488
Thank you in advance for your help with problem. I need to find 3 coordinates of 3 other points with this info. (5,-1) and the slope of m=-2/3.
:
Use the point/slope formula to find the equation using the above values
Formula is: y - y1 = m(x - x1)
:
In this problems x1=5; y1=-1
;
y - (-1) = {{{-2/3}}}(x - 5)
:
y + 1 = {{{-2/3}}}x - {{{-10/3}}}
:
y = {{{-2/3}}}x + {{{10/3}}} - 1
:
y = {{{-2/3}}}x + {{{10/3}}} - {{{3/3}}}
:
y = {{{-2/3}}}x + {{{7/3}}}
:
Choose some value for x that will give us integer y
:
Substitute for x and find y in the above equation; here's an example of this:
 x | y
-------
-1 |+3
+2 |+1
+5 |-1
+8 |-3
;
Did this make sense to you? Any questions?
