Answer:
y=-5x
Step-by-step explanation:
y-y1 = m(x-x1)
m= -5 and (5,-6) --> 5 is x1 and -6 is y1
Put the numbers in the formula
'simplify'
Subtract 6 from both sides
If you want to check your work to make sure it goes through the point (5,-6), I recommend using GeoGebra. It is free and you can use it on your computer or your mobile device
