The x-axis of the graph represents the number of monthly payments made, hence, the x - intercept which marks the intersection point of the slope line with the x - axis is 60 and gives information about the number of monthly payments needed to repay the loan.
Therefore, the value of the x-intercept is 60 and represents the number of monthly payments needed to cover the loan.

Answer:
Third choice
Step-by-step explanation:
The standard form of a circle is
where h and k are coordinates of the center and r is the radius squared. We have h = 2, k = 7, and r = 4 (we will have to square it to fit it into the equation properly). Filling in accordingly:
The third choice is the one you want.
a) The tangent to at
has slope
and at this point. It passes through the origin, so its equation is
It also passes through the point on the curve, so
By substitution,
b) The normal to at
has slope
It follows that
c) The tangent line equation is then
