Answer:
x=-6 + y= 3
Step-by-step explanation:
We are given coordinates of A, B, C and D :
A(2, 4), B(9, 8), C(-1, 2), and D(3, -5).
Now, we need to find the slopes of AB and CD.
Slope of AB is :



.
Slope of CD is:

.
<em>Slope of CD is negative reciprocal of slope of slope of AB. </em>
<h3>Therefore, lines AB are CD are perpendicular.</h3>

First convert all of the fractions into the same denominator. 1/3 = 2/6. Add the new fraction of history books and the fraction for english books. 2/6 + 1/6 = 3/6. Subtract the total from 1 or 6/6. 6/6 - 3/6 = 3/6. The answer is 3/6 or 1/2 when reduced. 50% or 1/2 of the books are science books.
