Find the slope of the line whose equation is px - qy = r. q/p p/q -r/q
Zina [86]

Answer:

The slope is equal to

m=\frac{p}{q}

Step-by-step 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=\frac{p}{q}x-\frac{r}{q} ------> linear equation into slope-intercept form

the slope is equal to

m=\frac{p}{q}

The y-intercept is equal to

b=-\frac{r}{q}

first you add 5 and 3 then you get 8

second you subtract the 8 you just got from the one in ( ) and you get 13=2x

Third you divide 13 and 2 and when you do that you get 6.5=X but if you not supposed to do it in a decimal form then is 13/2=X
