When janelle woke up, it was –3 degrees fahrenheit outside. as the morning progressed, the temperature rose 2 degrees every hour. which line on the graph could represent this scenario? a(x) f(x) g(x) h(x)

The line graph is shown below.

Step-by-step explanation:

Note: The options are not given.

It is given that Janelle woke up, it was –3 degrees Fahrenheit outside. As the morning progressed, the temperature rose 2 degrees every hour. It means,

Initial temperature = -3

Rate of change = 2 degrees every hour

The slope intercept form of a line is

where, m is slope and b is initial value or y-intercept.

Substitute m=2 and b=-3 in the above equation.

The table of values is

x      y

0     -3

1       -1

2       1

Plot these points on a coordinate place and connect them by a straight line.

The line graph is shown below.

-4

step-by-step explanation:

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
