Question

What are the coordinates of the `y`-intercept of the equation `y-7x = 8`?

Answer 1

`(0,8)`

Explanation:

In standard form `y=7x+8`.

Linear equation of form `y=mx+c` implies y intercept is `c`.

So `c=8` and coordinates are `(0,8)`.

Answer 2

( 0 , 8 )

Explanation:

when a straight line crosses the y-axis , the corresponding x-coord will be zero. By substituting x = 0 into the equation will obtain y-coord.

x = 0 : y - 0 = 8 hence y= 8

hence coordinates of y-intercept = ( 0 , 8 )

Note : A similar process can be used to find the x-intercept , except let y = 0.
