Question

I need help please take a look at this

Answer 1

`\\ \rm\hookrightarrow y=x-1`--(1)

`\\ \rm\hookrightarrow -x+3/2=-y`

`\\ \rm\hookrightarrow y=x-3/2`--(2)

Observe

Only b is different in both ones(y intercept)

Lines are parallel so no solution

Answer 2

`y = x-1`

`-x+\frac32=-y\\\implies y=x-\frac32`

The equations have the same slope but different y-intercepts. This means the lines are parallel and there is no solution (since they do not intersect).
