Question

Find the equation of the line passing through each of the following parts of points.
A(a,0),B(2a,3a)​

Answer 1

Answer:

3x - y -3a=0

Step-by-step explanation:

we know that equation of the line passing through points (x1,y1) and(x2,y2) is,

y-y1 = ((y2-y1)/(x2-x1)) × (x-x1)

points A and B  are given as,

(a,0) and (2a,3a) respectively,

so the equation will be,

y-0= ((3a-0)/(2a-a) × (x-a)

=>  y= (3a/a) × (x-a)

=> y= 3(x-a)

=> 3x - y -3a=0
