Question

A)Write the coordinates of the point on the line passing through the point A(2,1) and B(7,1).
b) write the coordinates of the point on the line perpendicular to the line passing through B(7,1).

Answer 1

Answer:

(7,1), (7,2), (7,3) etc.

Step-by-step explanation:

Answer 2

Answer: (5,1).

Step-by-step explanation: Given points are A(2,1) and B(7,1). To find any other point on the line joining A and B, we need to first find the equation of the line AB.

Slope of line AB is given by

$m=\dfrac{1-1}{7-2}=\dfrac{0}{5}=0.$

So, the equation of the line AB is

$y-1=m(x-2)\\\Rightarrowy-1=0(x-2)\\\Rightarrow y=1.$

Hence, another point on the line AB is (5,1), (3,1), (-4,1), etc.
