Like the majority of slope questions, we don't need to actually find the slope in order to get the right answer.
We can make a super rough sketch plotting the two points, draw a line connecting them, and then draw a line perpendicular to the first line.
The second line goes up and to the right. So is it positive or negative? Positive. A, B, and C are wrong.
Is the second line steeper than 45 degrees or not as steep as 45 degrees? Not as steep; slope has to be less than 1. E is wrong.
Answer choice D
