Question

The graph of equation 5x-3y=20 intersects the x-axis at point ......................

Answer 1

Answer:

4

Step-by-step explanation:

put y=0

then we find 5x=20

so x=20/5=4

therefore the point is (4,0)

Answer 2

The graph of equation 5x - 3y = 20 intersects the x-axis at point (4,0)

Given :

The equation of the line 5x - 3y = 20

To find :

The point where graph of the line intersects the x-axis

Solution :

Step 1 of 2 :

Write down the given equation of the line

The given equation of the line is

5x - 3y = 20 - - - - - - (1)

Step 2 of 2 :

Find the point where graph of the line intersects the x-axis

Since the line intersects the x-axis

∴ y = 0

Putting y = 0 in Equation 1 we get

5x - ( 3 × 0 ) = 20

⇒ 5x - 0 = 20

⇒ 5x = 20

⇒ x = 20/5

⇒ x = 4

Hence the required point is (4,0)

The graph of equation 5x - 3y = 20 intersects the x-axis at point (4,0)
