Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept)
given y + 2 = -
x + 
Subtract 2 from both sides
y = -
x +
- 
y = -
x -
← in slope- intercept form
1: multiple both sides by 2
Ex:-7n+10=-32
2: subtract 10 from both sides
Ex: -7n=-42
3:divide both sides by -7 to get n alone
Ex: n=6
Answer is 6 and the process is elimination!
2x+4y=8
-2x -2x
4y=-2x+8
/4 /4 /4
y=-1/2x+2
Answer:

Step-by-step explanation:
Given
Bisector: QS


Required
Determine PQR
Since PQR is bisected to PQS and RQS, we have that

Substitute expressions for PQS and RQS

Collect Like Terms


Divide both sides by 3

Solving for PQR;



Substitute 2 for x
