It's an exponential so we rule out the first one.
It increases with increasing x, so the base must be bigger than one; rule out the second choice.
It looks like (1,10) and (2,100) are on the graph, so that's the third choice,

Answer:
y = -3x
Step-by-step explanation:
the equation of the line would follow the formula y = mx + b, where m is the slope and b is the y-intercept. the slope is -3 so we would substitute that in for m. and since there is no y-intercept in this situation, our equation would be y = -3x.

Step-by-step explanation:
Small bag
95p / 250 g * 12/12 to get to 3 kg = 1140 p / 3000g =11.40£s/ 3 kgs
Medium bag
1.8£ / 500 g * 6/6 to get to 3 kg = 10.8£ / 3000g =10.80£/ 3 kgs
Large bag
3.7£ / 3 kg *
