Question

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

Answer 1

Answer:

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

Step-by-step 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)
