Question

What is kind of system of equation are 3x=4+5. 5x-y=11

Answer 1

Answer:

In order to represent the pair of  linear equation graphically we need two points on the line representing each equation.

⇒  Prepare the proper table of at least 2 solutions for both the equations.

5x−y=5

For x=0,

⇒  5(0)−y=5

⇒  0−y=5

⇒  y=−5

So we get co-ordinates (0,−5).

For y=0

⇒  5x−0=5

⇒  5x=5

∴  x=1

So we get co-ordinates (1,0).

x0 1 y −5 0 3x−2y=−4

For x=0

⇒  3(0)−2y=−4

⇒  −2y=−4

⇒  y=2

So we get co-ordinates (0,2).

For y=5

⇒  3x−2(5)=−4

⇒  3x−10=−4

⇒  3x=6

⇒  x=2

So we get co-ordinates (2,5)

x 0 2y 2 5 The given pair of linear equations intersect each other at point D(2,5).

The coordinates of the points where the line intersect y−axis are A(0,−5) and C(0,2).
