y = 40
Answer:
4) slope= 0
5) 
Step-by-step explanation:

4) Slope


= 0
The slope is zero as the line is a horizontal line (since both points have the same y-coordinate of 10).
5) Slope



Since you have taken (x₁, y₁) to be (9, 4), the value of x₁ should be 9 instead of 2.
The answer is 35000. Because 2 significant figures means the 2nd number, in this case it is the number 4 and if we want to round off something, look at the next number, if more than 5 or 5, you must round up.
