Find the slope of the line through (-4, -7) and (1, 3)

Solved by pluggable solver: Finding the slope


Slope of the line through the points (-4, -7) and (1, 3)



















Answer: Slope is




Now find the slope of the line through (2, 6) and (4, 10)

Solved by pluggable solver: Finding the slope


Slope of the line through the points (2, 6) and (4, 10)
















Answer: Slope is




Since the two slopes are equal, this means they are parallel
