Question
Give the geometrical representation of 2x + 13 = 0 as an equation in two variables .
Advertisements
Solution
Two variable representation of 2x + 13 = 0
2x + 0y + 13 = 0
2x + 13 = 0
2x = - 13
` x = (- 13)/ 2`
x = - 6 . 5
On Cartesian plane, equation represents all points y - axis for which x = - 6 . 5 .
