Answer:
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.

Answer:
35/37
Step-by-step explanation:
In this question, we are to calculate the ratio that represents the cosine of angle O
Firstly, please check attachment for diagram of the triangle.
Mathematically, the trigonometric term Cos means the ratio of the length of the adjacent to that of the hypotenuse
The hypotenuse is the longest length which is 37 which represents the length ON
The side adjacent to angle O is the side OP which is 35
Thus, the ratio representing the cosine of angle O is 35/37
