Just need help on this first one

Step-by-step explanation:

Since  x=0 is the equation of the y axis, a line parallel to this line is a vertical line.

In particular, vertical lines have the following type of equation:

x=k

where k is the value of the x coordinate of any of the points belonging to the line.

In this case, we want a vertical line that passes through a point with  x coordinate equal to -2 , so every other point belonging to this line must have this same coordinate, and the equation of the line is thus

x=-2

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .
