Question

P and Q are points on the line

4x + 2y = 8

Complete the coordinates of
P and Q

P (0,?)

Q(?,0)​

Answer 1

P(0, 4 ), Q(2, 0 )

Explanation:

To find P, with an x- coordinate of 0

Substitute x = 0 into the equation and solve for y

4(0) + 2y = 8 , that is

2y = 8 ( divide both sides by 2 )

y = 4

Thus P(0, 4 )

To find Q with a y- coordinate of 0

Substitute y = 0 into the equation and solve for x

4x + 2(0) = 8, that is

4x = 8 ( divide both sides by 4 )

x = 2

Thus Q(2, 0 )
