I’m sorry I do not know the other person was rude
Y = mx + b
b: y-intercept (when x equals zero)
m: slope ((y₂ - y₁) ÷ (x₂ - x₁))
Y - Intercept:
To find the y-intercept, just look at the table. The y-intercept is whatever y equals when x equals zero. In this case it is -8.
Slope:
(y₂ - y₁) ÷ (x₂ - x₁)
Pick two points and substitute them into this equation. Let's use (-3, 1) and (-2, -2).
(-2 - 1) ÷ (-2 + 3)
-3 ÷ 1
-3
Now substitute these values back into the equation.
y = mx + b
y = -3x - 8
The answer is a.
Answer:
24
Step-by-step explanation:
4 x 2 = 8 so 8 x 3 = 24
Answer:
A. T=7.12°C; B. t=3.32min
Step-by-step explanation:
In order to find the answer we can use the Newton's law of cooling:
where:
y0=initial temperature - room temperature
k=coefficients
t=time
Because the outdoors temperature is 3°C, the initial temperature is 20°C, and because the thermometer reads 11°C after 1min we have:



A. Temperature after an extra minute.

so the answer is 7.12°C
B. Time in order to read 4°C
