Find the slope of the line that goes through the points (-2,15) and (-1,-12)
enter the answer as an integer or a reduced fraction in the form a/b
:
The slope formula: m = %28%28y2-y1%29%29%2F%28%28x2-x1%29%29
in this problem:
x1 =-2; y1 = 15
x2 =-1; y2 =-12
:
m = %28%28-12-15%29%29%2F%28%28-1-%28-2%29%29%29
minus a minus is a plus
m = %28%28-12-15%29%29%2F%28%28-1%2B2%29%29 = %28-27%29%2F1
m = -27 is the slope

Slope of the line through the points (-2, 15) and (-1, -12)



m+=+%28y%5B2%5D+-+y%5B1%5D%29%2F%28x%5B2%5D+-+x%5B1%5D%29


m+=+%28y%5B2%5D+-+y%5B1%5D%29%2F%28x%5B2%5D+-+%28x%5B1%5D%29%29


m+=+%28-12+-+15%29%2F%28-1+-+%28-2%29%29


m+=+%28-12+-+15%29%2F%28-1+%2B+2%29


m+=+%28-27%29%2F%281%29


m+=+-27



Answer: Slope is m+=+-27
