Average t= - 34.44 °C.
Let T be the highest temperature:
T - t = 49.44 °C ==> T-(-34.44) = 49.44==> T+34.44 =49.44 ==> T =15 °C

Answer:
the slope is POSITIVE (answer A)
Step-by-step explanation:
The line goes through: (-1, -2) and ( 2, 1)
Then the slope can be calculated as:
slope = (y2 - y1) / (x2 - x1)
in our case:
slope = (1 - -2) / (2 - -1) = (1 + 2) / (2 + 1) = 3 / 3 = 1
Therefore, the slope is POSITIVE (answer A)
Answer:
a) y does NOT vary directly with x
b) y = 2.5x -6.5
Step-by-step explanation:
If variation were direct the ratios of y to x would be constant. They are not:
6/5 ≠ 11/7
y does not vary directly with x.

y changes by 5 from 6 to 11 when x changes by 2 from 5 to 7. Then the slope of the linear function rule is (change in y)/(change in x) = 5/2. Using a point-slope form of the equation of a line, we can write the rule as ...
y = m(x -h) +k . . . . . . . . for a line of slope m through point (h, k)
y = (5/2)(x -5) +6
y = 2.5x -6.5 . . . . . simplify
