What is the slope of a line that passes through the points -2 -3 5 4?

Slope of the straight line through the points (-2, -3) and (5, 4):

Between two points (x0, y0) and (x1, y1):

change_in_y = y1 - y0;

change_in_x = x1 - x0;

slope = change_in_y / change_in_x

→ slope = (4 - (-3)) / (5 - (-2)) = (4 + 3) / (5 + 2) = 7 / 7 = 1.
