Given are equation of a line and curve x = 4 and y

To find the points of intersection substitute x = 4 in y

This gives, y

Now square root on both sides of the equation.

Therefore y = √9 y = 3, -3.

Given are two equations of straight lines y = 1 and 3 x + 2 y = 8.

To find the points of intersection substitute y = 1 in 3 x + 2 y = 8.

This gives, 3 x + 2 *1 = 8; 3 x + 2 = 8 3 x = 6;

Divide by 3 on both sides of the equation.

Therefore x = 2
