A reciprocal, or multiplicative inverse, is simply one of a pair of numbers that, when multiplied together, equal 1. If you can reduce the number to a fraction, finding the reciprocal is simply a matter of transposing the numerator and the denominator so the answer is he used the recpriocal of the slope.

I hope this helps you

slope=y2-y1/x2-x1

slope=9-15/5-3

slope= -6/2

slope = -3

What is the correct answer to this question?<br><br> F/2=5/8

ANTONII [103]

Answer:

F = 1.25

Step-by-step explanation:

All you would have to do is cross multiply, so our equations starts at $\frac{F}{2} = \frac{5}{8}$ . We would now multiply F by 8 and 2 by 5. We now have 8F = 10. We can now divide both sides of the equation by 8 to get F = 1.25.
