Question

anonymous · Answer

i really need these answers to bring my grade up if u know them please message them to me

You'll get banned from OpenStudy for trading answers like that.  Also, you won't be able to do the problems by yourself in the future, and what you are doing in Algebra 1 is the foundation to nearly everything else.

Better that you learn how to do the problems!  Put one up, and I'll show you how.

ok thanks

whpalmer4 · Answer

So, what's the first problem?

anonymous · Answer

1.Write an equation in point-slope form for the line through the given point with the given slope

(8,3);m=6

a.y+3=6(x-8)
b.y-3=6(x-8)
c.y-3=6(x+8)
d.y+3=6x+8

whpalmer4 · Answer

do you know what point-slope form is?

anonymous · Answer

a little im not that good in algebra

whpalmer4 · Answer

it lets us write the equation for a line if we know the slope $m$ and any point on the line $(x_0,y_0)$:

$$y-y_0 = m(x-x_0)$$

so we have $m=6$ and our point is $(x_0,y_0) = (8,3)$

Good so far?

anonymous · Answer

i think so

mathmale · Answer

It's extremely important that you learn to recognize and to use these formulas.  I strongly suggest you make up a list of the formulas you've used in solving problems and refer to it often for review and practice.   Please, let's ditch the "I'm not that good at algebra" comment; it doesn't help you at all.  Good luck.

mathmale · Answer

All the data you need are already given:

the given point with the given slope

(8,3);m=6

and whpalmer has given you the appropriate equation.  What next?

anonymous · Answer

i know you have to plug in the numbers to get the equation but i get confused when doing that

whpalmer4 · Answer

Okay, so let's plug in those numbers!

first, plug in $m=6$:
$$y - y_0 = 6(x-x_0)$$next, plug in $x_0 = 8$
$$y-y_0 = 6(x-8)$$finally, plug in $y_0 = 3$
$$y-3=6(x-8)$$

Does that makes sense?

anonymous · Answer

a little

mathmale · Answer

whpalmer has taken all of the data and substituted it into the appropriate equation for the straight line.  What do you need to do next?

whpalmer4 · Answer

before we do that, is there anything that isn't clear about what I did?  do you see why each number went where it did?

whpalmer4 · Answer

you do have to remember that coordinates are listed in the order (x,y) (alphabetical order, as it turns out)

anonymous · Answer

i remember that but oh i see i think i get it now

mathmale · Answer

This discussion will prove to be much more valuable to you in the long run if you'd please take notes on it and refer to those notes often later on when you need to apply this procedure.

whpalmer4 · Answer

So, we have $$y-3=6(x-8)$$Does that match any of our answer choices?
$$a.y+3=6(x-8)$$
$$b.y-3=6(x-8)$$
$$c.y-3=6(x+8)$$
$$d.y+3=6x+8$$
