It’s the 3rd option!
-5 (the bubble shaded black), the arrow going left towards -9.
Hope this helps!
C.
he starts 6500 ft up do that's the b in y=mx+b.
the m is -250 because that's the rate, and it's negative because he's going down.
I am doing this test I will do it and I will give you the correct answer when I am done I think it's the last one but I am not sure soo wit an tell I finish the test
3x - 2y = 7
-2y = -3x + 7
y = 3/2x - 7/2....slope of this line is 3/2. A perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign. So the slope we need is -2/3 (see how I flipped the slope and changed the sign)
y = mx + b
slope(m) = -2/3
(-3,-2).....x = -3 and y = -2
now we sub and find b, the y int
-2 = -2/3(-3) = b
-2 = 2 + b
-2 - 2 = b
-4 = b
so ur perpendicular equation is : y = -2/3x - 4 <==
