What is the slope of the line with points (-2, 5) and (-5, 7)?

-1/2
0.75
1/2
1.25

The correct answer is: 1/2

The slope of a line is the measure of the change in y (vertical) direction over the change in x (horizontal) direction. To find the slope, we use the formula "slope = (y2 - y1) / (x2 - x1)", where (x1, y1) and (x2, y2) are the coordinates of the two points on the line. For the given points (-2, 5) and (-5, 7), we have (x1, y1) = (-2, 5) and (x2, y2) = (-5, 7). Substituting these values into the formula, we get slope = (7 - 5) / (-5 - (-2)) = 2 / (-5 + 2) = 2 / (-3) = -2/3.
