Question

Find the slope of the line whose equation is px - qy = r. q/p p/q -r/q

Answer 1

px - qy = r
-qy = -px + r
y = (-p/-q)x + (r/-q)
y = p/qx - r/q

ur slope is p/q

Answer 2

The slope is equal to

`m=(p)/(q)`

Explanation:

we have

`px-qy=r`

Isolate the variable y

Subtract
`px` both sides

`px-qy-px=r-px`

`-qy=r-px`

Divide by
`q` both sides

`-y=(r-px)/q`

Multiply by
`-1` both sides

`y=(px-r)/q`

`y=(p)/(q)x-(r)/(q)` ------> linear equation into slope-intercept form

the slope is equal to

`m=(p)/(q)`

The y-intercept is equal to

`b=-(r)/(q)`
