Answer:
y=-2/5x-3
Explanation:
y=mx+b
so, we can find the m by using the y over x method (aka rise over run)
y=-2/5x+b
we can find b by
y^2-y^1
-----------
x^2-x^1
so, basically,
5^2- -4^1 5-(-4) 9
-------------- -------------- --------
-2^2-1^1 -2-1 -3
so i think this is correct,
y=-2/5x+-3 or y=-2/5x-3
hope it helped ;)
