Answer:</h2>
<u>- Real and rational number</u>.
<h2>
Step-by-step explanation:</h2>
<em>It's a rational number because it can be represented by the integer of integer numbers. It's also a real number because rational numbers belong to the real set of numbers and the number doesn't contain an imaginary component (i).</em>

As you can see those two angles are supplementary which the sum of two angles = 180°
So,
(9a + 6) + 75 = 180
Subtract 75 on both sides:
9a + 6 = 105
Subtract 6 on those sides:
9a = 99
Divide 9 on both sides:
a = 11

The answer will be y=2x+1
