# Question #e7d7d

##### 1 Answer

See explanation

#### Explanation:

Compare to the standardised equation of a strait line

Where

Given:

Although not written the variable

So both lines have the same gradient (slope -> m=1)

As each 'crosses' the y-axis (y-intercept) in different places and they are parallel to each other they never cross, So there is not a common value

THUS IT IS

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I am only doing this for one of the equation. You can do the other one by following the same method.

For

Determine the x-intercept (crosses the x-axis at

Set

Subtract 1 from both sides

Determine the y-intercept (crosses the y-axis at

Set
