Explanation:

Your question is incomplete, as the equations or graph or table(s) were not given.

However, I'll give a general way of solving this.

Take for instance, the equations are:


y = (4)/(3)x - 1


y = (2)/(3)x - (1)/(2)

To do this, we start by equating both equations.


y = y

i.e.


(4)/(3)x - 1= (2)/(3)x - (1)/(2)

Collect Like Terms


(4)/(3)x - (2)/(3)x= 1 - (1)/(2)

Take LCM


(4x- 2x)/(3)= (2 - 1)/(2)


(2x)/(3)= (1)/(2)

Cross Multiply


2x * 2 = 3 * 1


4x = 3

Make x the subject


x = (3)/(4)

Substitute 3/4 for x in
y = (4)/(3)x - 1


y = (4)/(3) * (3)/(4) - 1


y = 1 - 1


y = 0

Hence:


(x,y) = ((3)/(4),0)
