Question 1111341: Use the given conditions to write an equation for the line in​ point-slope form and​ slope-intercept form.
Slope= -6, passing through (-6,-9)
------------------------
All i have so far is:
y+9
____ = -6
x+6

You can put this solution on YOUR website!
The slope-intercept form is:
++y+=+m%2Ax+%2B+b+
+m+ = slope
+b+ = y-intercept
-------------------------------
+m+=+-6+
So far I have:
+y+=+-6x+%2B+b+
Since I'm given the point (-6,-9):
+-9+=+-6%2A%28-6%29+%2B+b+
+-9+=+36+%2B+b+
+b+=+-45+
That gives me:
+y+=+-6x+-+45+
--------------------------
check answer:
+-9+=+-6%2A%28-6%29+-+45+
+-9+=+36+-+45+
+-9+=+-9+
OK
( your method would have worked also. You
used the general point-slope formula )
