I'm going to use the slope formula which is
m = (y2 - y1)/(x2 - x1)
where (x1,y1) and (x2,y2) are the two points the line goes through
Slope of line PQ
m = (y2 - y1)/(x2 - x1)
m = (-6 - 8)/(-5 - (-7))
m = (-6 - 8)/(-5 + 7)
m = (-14)/(2)
m = -7
The slope of line PQ is -7
Slope of RS
m = (y2 - y1)/(x2 - x1)
m = (0 - (-5))/(-2 - 3)
m = (0 + 5)/(-2 - 3)
m = (5)/(-5)
m = -1
The slope of line RS is -1
Because the slopes are NOT equal (one is -7 and the other is -1), this means the lines are NOT parallel.

Answer: Choice B) No, the lines have unequal slopes
I believe it would be -17m-4/8
Your doctor wants you to take 12 tablets per day.
Each tablet is 250 mg, so 4 tablets make 1g.
4 tablets x 3g = 12 tablets a day
The 3rd one. It is the line that shows the average of most of the points since it’s more in the middle.
