Hi there, we can tackle this problem by using the slope formula, or (y2 - y1)/ (x2 - x1), between two coordinates, and these are ordered as (x1, y1), or E = (0, -2), and (x2, y2), or that F = (3, 2.5). We can then substitute 2.5 for y2, -2 for y1, and then solve the numerator to give us 4.5 since -2 is multiplied by a negative sign, and so, it is a positive number. Now, we can substitute 3 for x2, and 0 for x1, and then we can solve the denominator to give us 3. Finally, we can divide the numerator (4.5), by the denominator (3), and we get our result: the slope is 1.5 for EF. Hope this helps.
