The answer is 45

The answer is 13. You substitute the x in 2x+5 with 4, because x=4 here. That would give you 2(4)+5. 2(4) is 8, 8+5 is 13. Hope this helped!
Answer:
you find the slope by putting the equation in slope intercept form y=mx+b
so you would subtract 2x and have 2y=-2x+8
then you would divide by 2 to get y be itself so
y=-x+8
So your slope is -1/1
