Answer:
Step-by-step explanation:
7) (4 , 7)
Slope of the line passing through (0, 3) and (2,5) = ![\frac{5-3}{2-0}=\frac{2}{2}=1](https://tex.z-dn.net/?f=%5Cfrac%7B5-3%7D%7B2-0%7D%3D%5Cfrac%7B2%7D%7B2%7D%3D1)
Point lying on this line will have the same slope
(0,3) and (4,7)
Slope= ![\frac{7-3}{4-0}=\frac{4}{4}=1](https://tex.z-dn.net/?f=%5Cfrac%7B7-3%7D%7B4-0%7D%3D%5Cfrac%7B4%7D%7B4%7D%3D1)
(4, 7) lies on this line.
8) (2 , 2)
Slope of the line passing through (-2,10) and (1,4) = -2
(2, 2) & ( 1, 4)
![Slope = \frac{4-2}{1-2}=\frac{2}{-1}=-2](https://tex.z-dn.net/?f=Slope%20%3D%20%5Cfrac%7B4-2%7D%7B1-2%7D%3D%5Cfrac%7B2%7D%7B-1%7D%3D-2)
(2, 2) lies on this line
