Question 1167335
.


An equation of a straight line in a coordinate plane which has the slope  m  and passes through the given point  P = (a,b)  is 


        y - b = m*(x-a).                      (1)



<pre>
Simply substitute the given data into equation &nbsp;(1), &nbsp;and you will get

    y-(-1) = (-5)*(x-6).         (2)


It is the equation in the &nbsp;"slope intercept form".


If you want to get the standard form equation, &nbsp;simplify&nbsp; (2):

   y+1 = -5x + 30,  &nbsp;&nbsp;or, &nbsp;equivalently,  &nbsp;&nbsp;5x + y = 30 - 1,

or, &nbsp;finally, &nbsp;&nbsp;5x+y = 29. 
</pre>

Solved.
