After one week it will be a total decrease of 175 milligrams
Y - 3 = -2(x+5)
y - 3 = -2x - 10
+3. +3
y = -2x - 7
Hoi!
To solve this, first plug in the values for x and y.
x = 2, so anywhere you see x, put 2 in its place.
y = 3, so anywhere you see y, put 3 in its place.

4 × 2 = 8

× 3 =


=
is your answer.
