Question

At what point the graph of the linear equation 5x + 4y =20 , cuts the Y-axis?​

Answer 1

Answer:

At the point, (0,5).

Step-by-step explanation:

When the graph of linear equation intersects the Y axis,

Abscissa or X coordinate = 0

Ordinate or Y coordinate = some real number.

So,

X = 0

Y = ?

Linear equation : 5X + 4Y = 20.

Substituting the value, X = 0 in the given Linear equation,

5(0) + 4Y = 20.

0 + 4Y = 20.

4Y = 20.

Y = 20/4 = 5.

Therefore, Y =5.

Now, we know,

X = 0

Y = 5.

Therefore, the point at which the graph of the linear equation 5x + 4y =20 intersects the Y axis is at (5,0).

Hope this helps!!!!!
