Write the standard form of the line that passes through (-1,-3) and (2,1)
Pie
Answer:

5 =  - 2x - y
To find this you must find the slope first:
\frac{y - y1}{x - x1}
which is, after performing some calculating is -2.

Next you need to set up your eqaution:
y - y1 = m(x - x1)
when you set it up, and substitute the variables for your slope and points you should get this:
y - ( - 3) =  - 2(x - 1)
y + 3 =  - 2x - 2
add 2 to both sides
y + 5 =  - 2x
subtract y from both sides
5 =  - 2x - y

Solve for x and y. they both have to be the same number for each equation
Elis [28]
Hey there! :D

y=2x-9

We can plug that in as y, since y is equal to 2x-9. 

5x-3(2x-9)= 23

Distribute. 

5x-6x+27= 23

-1x+27=23

Subtract 27 on both sides. 

-1x=-4

Divide both sides by -1.

x=4

Now, plug that in for y. 

y=2(4)-9

y=8-9

y=-1

 (4,-1) <== solution

I hope this helps!
