Subtract the y-coordinates. This is the rise.
Subtract the x-coordinates in the same order. This is the run.
Slope = rise/run.
Subtract the y-coordinates: -6 - 15 = -21. rise = -21
Subtract the x-coordinates in the same order:5 - 2 = 3. run = 3
slope = rise/run = -21/3 = -7
Z=kx, 30=8k, so k=30/8=15/4 and z=15x/4, so when x=4, z=15.
2/x-9. You must divide 2 by x first to follow the order of operations then subtract by nine.
Answer: y+6=-2(x-4)
Step-by-step explanation:
Point slope form: Y-y1=m(x-x1)
Answer: A) 40%
B)30%
Step-by-step explanation:
A) becase 4/9 as a percentage is 0.444444% and I rounded it to 0.4% then turned it into 40% cause its outta 100
