(both sixes get cancelled and the fives also get cancelled to get -1/1 = -1)
Somebody can estimate the length of a book by using a ruler and rounding it to the nearest whole number.
1x54=54
2x27=54
3x18=54
6x9=54
Answer:

Step-by-step explanation:
Slope is negative reciprocal when two lines are perpendicular
m1=1/2 therefore m2=-2
The equation of the line in point-slope form is given as

Here m=-2 and (x1, y1)=(-3, -1)
Therefore,

Answer:
