Answer:

9/7, 1/6, -3, 4/5

Step-by-step explanation:

Use the $gradient =\frac{rise}{run}$ formula to solve this.

4: $gradient = \frac{14-5}{8-1} = \frac{9}{7}$

5: $gradient = \frac{10-9}{2-(-4)} = \frac{1}{6}$

6: $gradient = \frac{-5-4}{6-3} = \frac{-9}{3} = -3$

7: $gradient = \frac{-1-(-5)}{7-2} = \frac{4}{5}$

The meaning of the question is

Let the unknown number be x

Therefore x+7=16-2x
Now 2x+x=16-7
3x=9
X=9/3
x=3
