Answer:
y = -⅔x +5
Explanation:
y = -0.666666667x+5
or
y = -⅔x +5
how?
well as you can see on the first box (0,5)
we can already know by this the equation will look like
y = _x +5
since if x is 0, we will already have +5
now onto the next box to help us
(1.5,4)
lets subtract 5 from 4 to find out what the slope will be
4-5=-1 and then divide that by our x
1 / 1.5 = -0.666666667
so our equation is
y = -0.666666667x+5
or
y = -⅔x +5
(not sure if you can understand from my explanation but please trust, this is right)
