Answer:
B
Explanation:
The lines are B. Neither.
To determine whether two lines are parallel, perpendicular, neither, or coinciding, we can look at their slope. The slope of a line is a measure of how steep the line is. It is calculated by taking the difference in the y-coordinates of two points on the line, and dividing it by the difference in the x-coordinates of those points.
In this case, the two lines have the equations y = -3x + 7 and y = 3x - 7. To find their slopes, we can plug in the coordinates of two points on each line, and then calculate the slope using the formula mentioned above.
For the first line, we can use the points (0, 7) and (1, 4) to calculate the slope:
Slope = (4 - 7) / (1 - 0) = -3
For the second line, we can use the points (0, -7) and (1, -4) to calculate the slope:
Slope = (-4 - (-7)) / (1 - 0) = 3
Since the slopes of the two lines are the opposite of each other (i.e. one is positive and the other is negative), the lines are not perpendicular or coinciding to each other. This means that they do intersect at a right angle, and are not parallel or coinciding. Therefore, the correct answer is B, neither.
