X^2/ 100 + y^2/ 25 =1 (x squared over 100 plus y squared over 25 equals 1) the y-intercepts are at: (-10, 0) and (10, 0) (0, 10) and (0, 5) (0, -5) and (0, 5)

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
