Answer:
Hey there!
Slope: 7-3/1-(-1), which is equal to 4/2, or 2.
Point slope: y-7=2(x-1)
So choice B is correct.
Let me know if this helps , or if you have any more questions :)
Answer:The amplitude:30
so a:-30
the period is:12
so b: pi/6
Step-by-step explanation:
Answer:
-9m - 4 + 2m = -9 - 7m + 5
-7m - 4 = -7m - 4
-7m + 7m = -4 + 4
0 = 0
This is an identity solution because the same number equals the same number. That means there's an infinite set of solutions.
I assume #3 is 19 because the slope of the line is still the same.
Hope this is right and it helps! I'm not very sure though.
7.5 would be my best guess
