Question

How can I find three ordered pairs of the equation y=3x-5?

Answer 1

Solution:

Given linear equation in two variables x and y :

y = 3x-5

i) if x = 0, then

y = 3×0-5 = -5

(x,y) = (0,-5)

ii) if x = 1 , then

y = 3×1-5 = 3-5 = -2

(x,y) = (1,-2)

iii)if x = 3 ,then

y = 3×3 - 5 = 9-5 = 4

(x,y) = (3,4)

Therefore,

Three ordered pairs are

(0,-5),(1,-2) and (3,4)
