Answer:
The slope is -2
Step-by-step explanation:
(−4,7);(2,−5)
(x1,y1)=(−4,7)
(x2,y2)=(2,−5)
m=
y2−y1
/x2−x1
−5−7
/2−4
−12
/6
−2
Answer:
x=-3, y=5
Step-by-step explanation:
6x + 2y = -8 3x - 2y = -19
Add the two equations together to eliminate y
6x + 2y = -8
3x - 2y = -19
------------------------
9x = -27
Divide each side by 9
9x/9 = -27/9
x = -3
Now we find y
6x + 2y = -8
6(-3) +2y = -8
-18+2y = -8
Add 18 to each side
-18+18 +2y = -8+18
2y = 10
Divide by 2
2y/2 = 10/2
y =5

Answer:
4. D
5. A
Step-by-step explanation:
For #4, I first divided 15 by 4 and saw what the greatest whole number it was divisiable by. Then I wrote the remain as a fraction
For #5, I first multiplied by 4*6 and then add 5 to that answer
