Question

The point of intersection the ones is called.
, , center
The graph of x-a is a straight line ​

Answer 1

intersecting line

and yes, the graph of x-a is a straight line

The point where the lines intersect is called the point of intersection. If the angles produced are all right angles, the lines are called perpendicular lines. If two lines never intersect, they are called parallel lines.

the graph of x = a is a straight line parallel to y-axis at a distance a from the y-axis, on the right if a > 0 and on the left if a < 0. (iv) Graph of y = a.
