The temperature in a crater on Mars is 0°C at 1 p. m. The temperature decreases 8°C every hour. When will the temperature be -50°C?
To determine when the temperature will be -50°C, ffind how long it will take the temperature to decrease by
50°C. Write and solve an equation to find the time.
ind how long it will take the temperature to decrease by 50 c. Write and solve an equation to find the time

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph
