What is a function?
Answer:
Step-by-step explanation:
Perpendicular lines have slopes that are opposite reciprocals of each other. In order to write the equation of a line perpendicular to the one given, we need to find the slope of the given line and then take the opposite reciprocal of it. The current form the line is in does not give us a clear idea of what the slope is. We will first put the given line into slope-intercept form (right now it's in standard form, which is not helpful for anything at all!). Solving the given equation for y:
12y = -2x - 1 and
(notice I reduced the slope's fraction from -2/12)
That means that the slope of the given line is -1/6. So the perpendicular slope is positive 6/1 or just 6.
Using that slope and the given point in point-slope form to write the equation:
y - 9 = 6(x - 0) and
y - 9 = 6x - 0 and
y = 6x + 9
There you go!

Step-by-step explanation:
The required tools are a compass and straightedge. A pencil or other drawing tool will also be useful (or you can use the marker in the compass).

Generally, follow the applicable directions. The specific directions vary, depending on the construction you want to do. Numerous web sites and videos can show you step-by-step. (Search for "construction of ...") for whatever you're trying to construct.

To construct a circle (or part of a circle), set the compass to the appropriate width, place the pointed end on the center of the circle, and rotate the marker in a circle around that point, taking care to ...
- keep the pointed end in the same spot,
- keep the width of the compass the same until your circle is complete.
To construct a line through two points, align the edge of the straightedge with the two points, and make a mark along that edge using your marking tool. (You may find that you need to make a slight adjustment in your alignment to account for the width of the marker).
All other constructions use combinations of these skills.
