Re: Point Slope Form of an Equation

Times both sides by 14.

Next step you do.

Re: Point Slope Form of an Equation

140 = 62311 + -31x



Add '31x' to each side of the equation.
140 + 31x = 62311 + -31x + 31x

Re: Point Slope Form of an Equation

-31x + 31x = 0
140 + 31x = 62311 + 0
140 + 31x = 62311

Re: Point Slope Form of an Equation

Add '-140' to each side of the equation.
140 + -140 + 31x = 62311 + -140

Re: Point Slope Form of an Equation

140 + -140 = 0
0 + 31x = 62311 + -140
31x = 62311 + -140
62311 + -140 = 62171
31x = 62171

Divide each side by '31'.
x = 2005.

Re: Point Slope Form of an Equation

Your welcome. I think you learned how to do it. Do not forget to thank Bob Bundy too when you see him.

Re: Point Slope Form of an Equation

hi zee-f

These last two posts made me laugh.  I wonder when you will 'see me'?  Maybe it'll happen one day (and I look forward to it! smile  ) but, in the meantime, here is a suggestion for you.

It seems to me, looking at your struggles with these questions, that you would have got on much better if the numbers had been simpler to start with.  And plottable on a graph where the axes go from -10 to +10.

If you would like some practice with such problems, I'm happy to make some up for you and check your answers.  I'll start with an easy one to give you some confidence, and gradually make them harder at a pace that suits you.

If you would like this, please post back.

Bob
