Question
Using the slope formula, find the slope of the line through the given points (7, 2) and (-3, -5).
Solution
The slope of a line through two points (x1, y1) and (x2, y2) is given by the formula:
m = (y2 - y1) / (x2 - x1)
Here, the two points are (7, 2) and (-3, -5). So, x1 = 7, y1 = 2, x2 = -3, and y2 = -5.
Substitute these values into the formula:
m = (-5 - 2) / (-3 - 7)
Simplify the equation:
m = (-7) / (-10)
So, the slope of the line through the points (7, 2) and (-3, -5) is 0.7.
