2x + 3y = 12
2x - y = 4
4y = 8
y = 2
2x - 2 = 4
2x = 6
x = 3
The coordinates are (3,2) and that is your answer :)
Answer:(-12-10i)
Step-by-step explanation: two negatives make a positive (1--1=2)
Answer:
C (the third one)
Step-by-step explanation:
Its probably right
A and B are proportional.
(3,6) (5,3)
(x1,y1)(x2,y2)
The slope equation is: y2-y1
---------
x2-x1
Replace with numbers: 3-6/5-3
Minus 3 and 6 is equal to -3
Minus 5-3 is 2
So the fraction is -3/2 (no need to divide because you can't simplify it)
So the slope is -3/2
For the equation you have to replace the letters by 0's
3×0-2y=6
Times 3 and 0
0-2y=6
Now you want to get the y alone, so minus 0 from both sides
0-2y=6
-0 -0
-2y=6
Divide -2y from the 6
-2y=6
---- ---
-2 -2
y=3
The y intercept is 3 with the slope of -3/2
