Question

The relationship between antioxidant food consumption per day in cups and the BMI of an individual is modeled by the following line of best fit: y= -1.2x+26. Interpret the slope and intercept of the trend line within the context of the data.

Answer 1

This is in gradient intercept form (or slope intercept form)
y = mx + b
in this case y = -1.2x + 26
so m (the slope) = -1.2
and the y intercept = 26
I'm not sure what intercept they're asking for.
if you wanted to find the x intercept, just substitute.
y = 0 and find x.
