Answer: y=-2x+-5

Step-by-step explanation:you multiply 2 by -2 and get -4. Then you add 4 to cancel out the 4 and b equals -5. Then you just put it in slope intercept form.

y=mx + b = (-2)x + b

Now substitute the x and y-values from the given point:
-9=(-2)(2)+b
Isolate the variable b:
b=(-9)-(-2)(2)=(-9)-(-4)=(-9)+4=-5

Now put it all together:
y=-2x-5
