Answer:

Step-by-step explanation:
We are given the line y=2x+8. It is in slope-intercept form or y= mx+b, where m is the slope and b is the y-intercept.
The slope of the line is 2.
We want to find the equation that is perpendicular. Perpendicular lines have negative reciprocal slopes.
1. Negate
- Negate the slope, or switch the sign
- (+) 2 --> -2
2. Reciprocal
- Flip the numerator and denominator of the slope.
The perpendicular slope is -1/2, so the correct equation must be B.
The answer is 64.4 because you multiply 92 times 0.7 and get 64.4
If a big quadrilateral is a square.
Look at the picture.
16 + 4 + 3 + 8 + 4 + 5 = 40
