Write a ratio expressed in the slope of the line through each pair of points (-6,-4) and (21,5)
The slope of a line can be found using the formula:
m = (y2 - y1) / (x2 - x1)
Using the points (-6,-4) and (21,5), the slope can be calculated as:
m = (5 - (-4)) / (21 - (-6))
= (5 + 4) / (21 + 6)
= 9 / 27
= 1/3
Therefore, the ratio expressed in the slope of the line through the points (-6,-4) and (21,5) is 1/3.
