Y-6=-6(x+5)
y-6=-6x-30
y=-6x-24 is the answer
The standard form of the equation of a circle is:

Where the point (a,b) represents the centre and r is the radius. So, given your information, the equation will be:
You could answer this question easily by applying synthetic division:
_______________
-5 / 4 14 -9
-20 30
---------------------------
4 -6 21
Just plot the points on the graph.
2. You know since the graph is a straight line, the ratios are proportional and therefore equivalent
