Find the equation please help me

y=-2/5x-3

Step-by-step 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 ;)
