Question

please answer..its so important. please.

Draw the graph of each of the following linear equations in two variables:
(i) x+y=4 (ii) x - y = 2 (ii) y= 3x
(iv) 3 = 2x + y

need 3 points to plot. please answer..
​

Answer 1

Answer:

To draw the graph, we need atleast two solutions of the equation.

x 0 4

y 4 0

(x, y) (0, 4) (4, 0)

Thus, we draw the graph by plotting the two points from table and then joining by a line.

ii) To draw the graph, we need atleast two solutions of the equation.

x 0 2

y -2 0

(x, y) (0, -2) (2, 0)

Thus, we draw the graph by plotting the two points from table and then joining by a line.

iii)To draw the graph, we need atleast two solutions of the equation.

x 0 1 -1

y 0 3 -3

(x, y) (0, -2) (2, 0) (-1, -3)

Thus, we draw the graph by plotting the two points from table and then joining by a line.

iv)To draw the graph, we need atleast two solutions of the equation.

x 0 1 -1

y 3 1 5

(x, y) (0, 3) (1, 1) (-1, 5)

Thus, we draw the graph by plotting the two points from table and then joining by a line.
