Answer:
y= -1.5x-7 is the equation of the perpendicular line
Here's why:
when we convert 2x-3y=8 to standard form, we get y= 2/3x-8/3. This means the perpendicular line will have a slope of the negative reciprocal of the original one, so the perpendicular slope is -1.5. When we substitute the points (-2,-4) into the equation y=-1.5x+b, we get a b value of -7. So the perpendicular line equation is y= -1.5x-7. You can't the parallel line equation with the points (-2,-4) as it is part of the line 2x-3y=8.

Answer:
9 sides
Step-by-step explanation:
Originally Answered: The measure of each interior angle of a regular polygon is 140 degrees. How many sides does a regular polygon have? this means that each slice covers an angle of 180-140=40 degrees with redpect to the polygon centre. hence there are 9 sides.
