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.
Answer:

Step-by-step explanation:
the slope is :

at a pt on graph , when

therefore, coordinates are (1,3)
The equation is :

Pick a value for 'x' then solve for the 'y'
Ex: X=6 then 6-2y=2 then 4=2y then y=2y
So your answer will be 6,2.
Another answer to your question would be 4,1.
