The students want to find a cooler that keeps the temperature inside the cooler more than 3 degrees below the freezing point of water (0ᵒC) after 90 minutes. Indicate which of the tested coolers meets this goal, and explain why.

depending on others is critical to survival. my source is apex!

step-by-step explanation:

your answer is option c.

d

step-by-step explanation:

the two points from this line are   (0,4)   & (2,-2)

we can call

now, lets find the slope (m):

now finding b (the y intercept). this is the point at the y-axis where the line cuts the axis. looking at the graph, it is y = 4. so the point is 4. hence b = 4

the slope-intercept form is given by  

putting the points, we have:

d is the correct answer.

the answer is d=3.09
