Answer:
The value of the x-coordinate is -3.5.
Step-by-step explanation:
To determine the x-coordinate you have to look at how far the point is on the x-axis which is the sideways line of the graph.
Point W is between -3 and -4 on the x-axis which would make the x-coordinate -3.5.
Hope this helps!

The distance formula is the square root of (X2 - X1)^2 + (y2 - y1)^2. Let D = y and c = x. Plug in the numbers now. Your equation is now the square root of ( -3 - (-5)) ^2 + (-2 - (-4))^2. Now complete it, your answer is 2.82...
When the slope isn't defined, it's not possible to write the line in slope-intercept form. No slope means a vertical line, which here must be

The ordered pair (-1,6) obviously satisfies the above equation so is on the vertical line
.
Answer:

Step-by-step explanation:
Given the equation of the circle: 
We wish to express it in a Standard form:
We begin by re-arranging:

Next, divide the coefficient of x by 2, square it and add it to both sides.
Do the same for y.

Next, we factorize

This is the standard form.
