What is the slope of the line through (-1,-7) and (3,9)

Answer 1

The slope of a line passing through two points, (x1, y1) and (x2, y2), is given by the formula:

Slope = (change in y) / (change in x)

In this case, we have the points (-1, -7) and (3, 9):

change in x = 3 - (-1) = 4
change in y = 9 - (-7) = 16

So the slope of the line passing through (-1, -7) and (3, 9) is:

Slope = (16) / (4) = 4
