Side AB and side AD are perpendicular because they cross at a ninety degree angle, and the sides are also the same length.
Answer:
y = 5/6x + 2.5
Step-by-step explanation:
slope = m = rise/run
equation format - y=mx+b
slope/m= 5/6
y=5/6x+ the y-intercept
the y-intercept is at 2.5
so the full equation would be \/\/\/
y = 5/6x + 2.5
It is always because if you have an improper fraction, the larger number is always the numerator. To get a reciprocal, you flip the fraction so that the denominator is the numerator, and vice versa. If the numerator is always bigger, and you make it the denominator, it would be proper.
You have to simplify.
-d-3=-2-2d
-1=-d
d=1
