Question 529288
Could you find another point on a line with this points: (0,18000) (8,4500);Also how do you find the slope of this line?
<pre>

We'll find the slope first:

m = {{{(y[2]-y[1])/(x[2]-x[1])}}}


m = {{{(4500-18000)/(8-0)}}}

m = {{{(4500-18000)/(8-0)}}}

m = {{{(-13500)/8}}}

m = {{{-3375/2}}}

Now we use tio point-slope form:

y - y<sub>1</sub> = m(x - x<sub>1</sub>)

y - 18000 = {{{-3375/2}}}(x - 0)

y - 18000 = {{{-3375/2}}}x

y = {{{-3375/2}}}x + 18000

Just substitute random values for x into that equation,

(2, 14625),  (-6,28125), (-500,861750), 

(10,1125), (8,4500), (2222,-3731625)

Those are all points on the line.
