Question
Give the geometric representation of the following equation
(a) on the number line (b) on the Cartesian plane : 2x + 9 = 0
Advertisements
Solution
2x + 9 = 0
2x = -9
` x = (-9) / 2 = - 4 . 5 `
Point A represents - 4 . 5 on number line
On Cartesian plane, equation represents all points on y - axis for which x = - 4.5
