notice the colors:
now do you see what to do?
yes2) Find an equation for the given points on a line (-2,-3) and (5,-4).
Is it y= -1/7(x) - 23/7?
the equation of a circle with center and radius is given by:3) Find an equation of a circle with center (-2,-3) tangent to the line y=7
we want this circle to touch the line at one point. think of how large the radius must be to touch the line
