2x+6 geometric representation on 2 variables -Maths 9th
by

1 Answer

Answer :

2x+6 = 0in two variables is 2x + 0y + 6 = 0 Here, all the value of y can be taken as product of 0 and y is always 0. Now, x must satisfy the equation 2x+6 = 0 ⇒ 2x = -6 ⇒ x = -3 Thus, x = -3 and y = 0 The graph obtained will be a line parallel to Y-axis at a distance of -3 on X-axis.
