12. y = -2x
Step-by-step explanation:
to find the slope-intercept formula of these charts: (i'm guessing that that's what your teacher wants? you forgot to include their directions in the images)
you need to use y = mx + b
to find m, you take two coordinates and then do (y2 - y1)/(x2 - x1)
to find b, figure out what y is when x = 0.
you can either do this by looking at the chart and finding 0 on the x side, or if that isn't there, take a different point and insert the y and x values into what you have so far. if you enter the points correctly and have an m, the only letter you should have left is b. so all you'd need to do from there is solve the equation for b!
hope this helped!!

Answer:
It's the bottom one.
Step-by-step explanation:
number one makes no snese because inside of you there is no light
number two, heat and thermal are the same thing
number three, there isn't really potential energy inside you, not in the process of the energy transformation of food.
The bottom one makes the most sense because if you think about all of the steps, it goes chemical (stomach acid), there is also some heat in there, and then mechanical when the food moves from place to place
