I think its the second one, the answer does not have a definite and, and cannot be put into a ratio.
To be parallel, this new line has to have the same slope as the other. To find the slope, we look at the number multiplying x.
-x means x is being multiplied by -1, so the slope, or m, is -1.
y = -x + b
Now, input the coordinate point and solve for b.
-2 = -1(2) + b
-2 = -2 + b
Add 2 to both sides.
0 = b
y = -x
<h3><em><u>The equation to find the number of hours for which the total cost will be the same for the two services is:</u></em></h3><h3>12 + 5h = 18 + 3h</h3>
<em><u>Solution:</u></em>
Let "h" be the number of hours
Given that,
<em><u>Derrick's Dog Sitting charges $12 plus $5 per hour</u></em>
Cost : 12 + 5(number of hours )
Cost : 12 + 5h ---------- eqn 1
<em><u>Darlene's Dog Sitting charges $18 plus $3 per hour</u></em>
Cost: 18 + 3(number of hours)
Cost: 18 + 3h ---------- eqn 1
<em><u>For eqn 1 = eqn 2, the number of hours for the total cost will be the same for the two services</u></em>
Therefore,
12 + 5h = 18 + 3h
Thus option A is correct
Ok....so look at the attached picture
