    the points (-5,-4) and (7,-5).

@Hero

aum · Answer

First find the slope of the line from the two given points.

If $(x_1,y_1)$ and $(x_2,y_2)$ are the two given points, 
then the slope $\Large m = \frac{y_2-y_1}{x_2-x_1}$.

What is the slope m?

texaschic101 · Answer

you figure out the slope yet ?

masumanwar · Answer

We can solve this equation for y= mx+c

anonymous · Answer

@aum @texaschic101 @masumanwar 
does m=5

aum · Answer

(-5,-4) and (7,-5) are the two given points.
$\Large m = \frac{y_2-y_1}{x_2-x_1} = \frac{-5-(-4)}{7-(-5)} = \frac{-5+4}{7+5}=?$

anonymous · Answer

that equals m=-1/12 @aum
im sorry i was busy chattin with my fans

can u help meh pls *-*

anonymous · Answer

well @aum does the computation for you, all you have to do is perform the arithmetic operations to solve for m, then using any of the points given... using the point-slope formula of a line$$(y-y_1)=m(x-x_1)$$you can have the equation of the line...

anonymous · Answer

wut im xD

anonymous · Answer

can u explain that 2 meh @Orion1213

anonymous · Answer

the two given points as we all know form the line, both of them lie on the line that we are looking for so they both satisfy the equation of the line... there is only one slope m, that you have obtained already... plug-in m and the coordinates of the point in place of $x_1$ and $y_1$ in the point-slope formula i gave above...

anonymous · Answer

so is it y=1/12x-or +b

anonymous · Answer

your slope is negative i think...

anonymous · Answer

oh ok so is it y=1/12x-b

anonymous · Answer

the final form is the slope-intercept form wherein you are familiar$$y=mx+b$$

anonymous · Answer

let us check: $P_1~(-5,-4)$ and $m=-1/12$$$(y-(-4))=-\frac{1}{12}(x-(-5))$$$$y+4=\frac{-x-5}{12}$$$$y=-\frac{1}{12}x-4\frac{5}{12}$$$$y=-\frac{1}{12}x-\frac{53}{12}$$

anonymous · Answer

you must get the same equation once you plug-in the other point (7,-5)

anonymous · Answer

hmmm
interesting soo
sooo y=-1/12x-53/12 is tha answer or do I have 2 divide

anonymous · Answer

Write the equation 5x - y + 6 = 0 in standard form with integer
    coefficients.
@Orion1213 
can u help meh with this pls

anonymous · Answer

is it Y=5X+6

anonymous · Answer

Ax + By + C = 0 is the standard form of a line...

anonymous · Answer

A, B and C are the integer coefficients...
