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

ur slope is p/q

Answer:

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)
