Answer:
y= -4x+5
Step-by-step explanation:
We can see that for everytime the x value increases the y value decreases by 4
This means that in our equation y=mx+b
m (our slope) = -4
Now it's just a matter of solving for b
you can do this by pluggin in a coordinate
(1,1) for example
1= -4*1+b
1= -4+b
b=5
Therefore the equation is y= -4x+5
