The slope of line s is; (0 - a)/(c - 0) = -a/c
<h3>What is the Slope of the Line?</h3>
The formula for slope of a line is;
m = (y2 - y1)/(x2 - x1)
For coordinates of two points labelled as; (x1, y1) and (x2, y2).
Thus, for the line s given on the graph, we can say that;
Slope = (0 - a)/(c - 0)
Slope = -a/c
Thus, the correct option to find the slope of line s is;
(0 - a)/(c - 0) = -a/c

Since Carmen gives two coins to Frankie for every five that she gets, she effectively only gains 3 coins at a time. Therefore, if she has 9 coins, Frankie must have 6.
Answer:
ab = 1
Step-by-step explanation:
A Reciprocal of a number is a number which when multiplied by the original number yields the multiplicative number, 1.
So the reciprocal of x would be x⁻¹ or ¹⁄ₓ
The information we are given states that the sum of the two non-zero numbers a and b equals the sum of their reciprocals.
So we can write this into an equation and solve,
(See image)
Once we solve, we get the equation (ab-1)(a+b) = 0
We are given info that a+b≠0
So for the above equation to be true, ab-1 has to equal 0
For <em>this</em> to be true, the product ab must equal 1
