david's procedure is correct becsuse Keisha didnt put the correct value of sin theta in equation, she forgot to mention negative sign. though solution are same but in other case it could have gone wrong
Answer:
#2 is a ratio so you gotta add.
#3 it’s just adding it for example 2p + 5a = 7pa
Answer: y = -9x - 9
First, you need to put the two equations into slope intercept form (y=mx+b.)
1) y= -9x + 9
2) y= -10x - 9
First take the slope of #1
m = -9x
Then take the y-intercept of #2
b = -9
Now, put it into an equation.
y = -9x - 9
