X=0.84....................
I’m pretty sure it would be 1/5, because scaling is changing the y values of the function. If the y value of the original is 10, you need to multiply/scale the new one by 1/5 to get the y value of 2
There is a way and you will find it but not from me
-m-4=-13
-m=-13+4=-9
m=9
