Question

Solve graphically y-x+2=0 and x-2y-4=0

Answer 1

Answer:-find like this putting of x and y .and plot on graph. I hope this was helpful

Answer 2

Answer:

(0, -2) is the solution

Step-by-step explanation:

Hi,

Given set of linear equations are

y - x + 2 = 0 -----(1) and

x - 2y - 4 = 0------(2)

Drawing the line y - x + 2 = 0 on the graph

Put y = 0 in the above equation (1), we get x = 2

Let A be (2, 0)

Put x = 0 in the above equation (1), we get y = -2

Let B be (0, -2)

Plot the points A(2, 0) and B(0, -2) on the graph sheet and draw a line

joining points A and B

Drawing the line x-2y - 4 = 0 on the graph

Put y = 0 in the above equation (2), we get x = 4

Let C be (4, 0)

Put x = 0 in the above equation (2), we get y = -2

Let D be (0, -2)

Plot the points C(4, 0) and D(0, -2) on the graph sheet and draw a line

joining points C and D.

We can clearly observe that both the lines intersect at common point

B(0, -2) which is the solution for the given set of equations.

Hope, it helps !
