Question 940312
Find the point, x=-2  and y=-5.
That point is shown here with the red and green squiggle:

{{{graph(200,200,-10,5,-10,5,-5+sqrt(0.02-(x+2)^2),-5-sqrt(0.02-(x+2)^2))}}}



Slope with of vertical change 3 and horizontal change 1 drawn from that point:


{{{graph(200,200,-10,5,-10,5,-5+sqrt(0.02-(x+2)^2),-5-sqrt(0.02-(x+2)^2),3x+1)}}}
That blue line intersects the y-axis at y=1.
