Answer:
a) Not parallel to y-axis
b) Not parallel to y-axis
c) Parallel to y-axis
Step-by-step explanation:
The best way to check whether a line passing through two points is parlle to y-axis is by plotting them on graph.
The equation of line: ![(y-y_1) = \frac{y_2 - y_1}{x_2 - x_1}(x-x_1)](https://tex.z-dn.net/?f=%28y-y_1%29%20%3D%20%5Cfrac%7By_2%20-%20y_1%7D%7Bx_2%20-%20x_1%7D%28x-x_1%29)
a) The line joining the points (4,12) and ( 6,12) is not parallel to y-axis.
It is parallel to x-axis. Another two points that can lie on this line are : (5,12) and (
,12).
b) The line joining the points
is not parallel to y-axis.
Equation of line: ![5y - 7.5x = 5.5](https://tex.z-dn.net/?f=5y%20-%207.5x%20%3D%205.5)
Another points that could be lie on this line are (0.6,2) and (0.25,1.475)
c) The line joining the points
is parallel to y-axis because points have the same x-coordinate.
Another points that could be lie on this line are (0.8,2) and (0.8,2.1)

46 hours after 9:30 p.m. on Friday will be J. 7:30 p.m. Sunday.
Since 46 hours is almost two days, you just need to take away those two hours, and you will get the time you need, two days after the original day.
Answer:
equation can be used to represent the possible ways that Jeremiah and Samantha can split the 38 apples? y=×+38
Answer: $21.12
Step-by-step explanation:
From the question, we are informed that Paul bought 12.8 pounds of apples at the farmer’s market and that each pound of apples cost $1.65.
To calculate the total cost of the apples, we use the multiplication operation. This will be done by multiplying the pounds of apple bought by the cost of each pound. This will be:
= 12.8 × $1.65
= $21.12
