The equation for the slope of a line is:
y2-y1/x2-x1
So:
-4-1/1-2 = -5/-1 =5
The slope of the line is 5.
To find the answer,we can set up an equation with an unkown:
Let the recommended daily amount be y mg
y×27% = 650
y×27/100 = 650
y = 650 ÷ 27/100
y = 650 × 100/27
y = 2407.407407...
y ≈ 2407
Therefore, the answer is 2407 mg.
