Answer:
The equation of the horizontal line passing through (4, 9) will be:

Please also check the attached line graph.
Step-by-step explanation:
We know that the equation of a horizontal line is always the kind of equation such as:

- As in the pint (4, 9), ordinate is 9.
- In other words, y=9
Thus, the equation of the horizontal line passing through (4, 9) will be:

Answer:
27.44 square cm
Step-by-step explanation:
If the length of parallelogram is a and b and angle between side a and b is .
Then area of parallelogram =
Given side length 4 cm and 7 cm
angle between them = 100°
value of sin(100°) = 0.98
Thus, area of given parallelogram = 4*7*sin(100°) = 28*0.98 = 27.44
Thus, area of given parallelogram is 27.44 square cm.
