Step-by-step explanation: To find the slope given two points we can use the following expression
above we have that:
m = slope
x1 and y1 = the coordinates for the first point
x2 and y2 - the coordinates for the second point
Question 1: Let's calculate as follows
Question 2:
Question 3:
Question 4:
Final answer: So the final answers are
1. -3/4
2. -1/3
3. 0
4. 0
