Answer:
D
Step-by-step explanation:
it's the only one that is actually correct along with having the decimal in the right spot.
That one is self-explanatory if you follow a video on it it will help
When your finding square roots all you need to do is find what same numbers multiply up to that number, you did the square root of 49 correctly but the square root of 34 is 5.83 and the square root of 45 is 6.70.
and the division does that say 13 divded by 7?
(-4,5)(3,-9)
slope = (-9 - 5) / (3 - (-4) = -14 / (3 + 4) = -14/7 = -2
y = mx + b
slope(m) = -2
use either of ur points...(-4,5)...x = -4 and y = 5
now we sub and find b, the y int
5 = -2(-4) + b
5 = 8 + b
5 - 8 = b
-3 = b
so ur equation is : y = -2x + (-3) which can be written as : y = -2x - 3
