How to find X where there’s 8 and base 8 in a right angle triangle

In this context, you would be making a equation using the format: y=mx+b

M being your rate of change

X being the month

B being the starting number

Beverly is LOSING 4 pounds a month, so she would be decreasing by 4, or in other words, -4. That would be your M value

Beverly starts at 160, so that would be your B value

Your equation would look like this:

y= -4x+160

Your answer would be B. y = -4x +160

A) is not the answer because you can't be -160 pounds

C) is not the answer because the 1 is not part of the text.

D) is not the answer because 160 has to be used in the equation in order for it to make sense, you don't start at 0 pounds.
