I think it's 30 meters
I hope it helps
The answer is 15. 37 plus 18 equals to 55 and 22 plus 18 equals to 40. 55 minus 40 equals to 15.
Negative 72.75 is your product. It is very simple once you understand it.
The equation for the stand form of a line is y = mx + b.
You will need
m = slope
b = y-intercept
The question already gave you both of those so you simply put them into the equation "y=mx+b"
m = -1/2
y-intercept = 1
Plug those into "y = mx + b"
Your equation is: y = -1/2x + 1
