The correct answer is D, y = 7x + 5
Calculate the slope by doing y2 - y1 / x2 - x1
y2 - y1 / x2 - x1
61 -33 / 8 - 4
28 / 4
7
Next find the y intercept by looking at the graph, which is 5 in the case
Put it together and you have y = 7x + 5, or option D

The question says they will run less than 36 miles, so this means they will run up to 35 miles.
They have run 22 so far, so t will be less than or equal to 35 - 22
T is less than or equal to 13.
Answer:
a) T= 0.25 C+37
b) T= 62°F
Step-by-step explanation:
Here T is a linear function of C
T= mC+b
For each additional chirp C corresponding to an increase in T of 0.25
therefore, m= 0.25
T= 42° F C=20 ( given)
therefore,
a) 42= 0.25×20+b
b= 37
therefore T= 0.25 C+37
b) now C= 100
therefore, T= 0.25×100+37 = 62°F
