For each pair of points below, think about the line that joins them. For which pairs is the line parallel to the y-axis? Circle
zaharov [31]

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)

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 (\frac{9}{2},12).

b) The line joining the points (\frac{3}{5}, \frac{13}{5}), (\frac{1}{5} ,\frac{8}{5}) is not parallel to y-axis.

Equation of line: 5y - 7.5x = 5.5

Another points that could be lie on this line are (0.6,2) and (0.25,1.475)

c) The line joining the points (0.8, 1.9), (0.8,2.3) 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)
