Question

Solve graphically: x + y = 0; 2x – 3y = 10. Find the area of triangle formed by
these lines and the X-axis. ​

Answer 1

x + y = 0 2x - 3y = 10

x. - 5 -3 - 4 x 5

y 5 3 4 y 0

(x,y) (-5,5) (-3,3) (-4, 4) xy. (5,0)

You can find numbers by this method

You have to just put any value of x and y

But condition is that for example x + y = 0 = 0 answer is required on putting any value in x or y

Answer 2

The area of the triangle is 5 cm ²

Step-by-step explanation:

given equation

x + y = 0

putting x = 0 we get y = 0

coordinate (0,0)

putting x = 2  we get y = -2

coordinate (2,-2)

similarly

2x – 3y = 10

putting  x= 5 , y = 0

coordinate (5,0)

putting x = 2 , y = -2

cooridnate (2,-2)

plotting these points on the garph we get the triangle  ABC

therefore , the area of triangle ABC

= $\frac{1}{2}\times base \times height$

= $\frac{1}{2} \times 5\times 2$

= 5 cm ²

hence , The area of the triangle is 5 cm ²
