Question

The co-ordinates of the point where the line y=x+4 crosses the y-axis​

Answer 1

Therefore the required point where it crosses y-axis is (0 , 4)

Explanation:

Given:

`y=x+4` ...............Equation of line

Intercepts:

The line which intersect on x-axis and y-axis are called intercepts.

There are two intercepts:

x-intercept: The line which intersect at x-axis. So when the line intersect at x-axis Y coordinate is zero.

y-intercept: The line which intersect at y-axis. So when the line intersect at y-axis X coordinate is zero.

For a line crosses Y-axis we have,

`y=x+4`

Put x = 0 in above equation we get

`y=0+4=4\\y=4`

Therefore the required point where it crosses y-axis is (0 , 4)
