Answer:

x-y

Step-by-step explanation:

First you must distribute:

4(x-y)= 4x-4y

-3(x-y)=-3x+3y

4x-4y-3x+3y

Then combine like terms:

(be careful of negatives)

4x-<em>4y</em>-3x+<em>3y</em>

Find the equation of the line that passes through both (5,1) and (8,-2)

Georgia [21]

Let $f(x) = ax+b$ be the line that passes through both points.

We know that $f(5) = 1$ and $f(8) = -2$ . So:

$\begin{cases}5a+b = 1 \\ 8a+b = -2\end{cases}$

Solving the system, we get that a= -1 and b = 6.

So the line is equal to $f(x) = 6-x$ .

15 POINTS!

joja [24]

8x + (2x - 14)= 7x + 3x -14

10x -14= 10x - 14

These equations are identical, so it would be the identity property and the answer would either be identity or the fancy 'R'.
