Suppose the line of best fit for the height, y, of a plant measured in millimeters after receiving x hours of sunlight is y = 1.7x + 9.7. What is the
meaning of the slope of the line of best it?

The plant is initially 1.7 millimeters tall,

The plant is initially 9.7 millimeters tall.

The plant grows at a rate of 17 millimeters for every 10 hours of sunlight it
receives

Astudent is determining the influence of different types of food on the growth rate of spiders. she feeds one group of spiders two caterpillars twice a week. the other group received similarly-sized beetles twice a week. she records the amount of time required for individuals to reach sexual maturity. her hypothesis is that the spiders feeding on caterpillars will have a faster growth rate because caterpillars have a higher protein content compared to beetles. in this experiment, what is the dependent variable? spiders assigned to different feeding groups. time required to reach sexual maturity number of prey items fed twice a week. growth rates of each group.
