Question

How do you graph a line with one number y= -4

Answer 1

Answer:

See explanation

Step-by-step explanation:

When you have an equation like that, all you have to do is draw a line at the y-value given. In our case, y = -4 is a horizontal line. Graph paper is made of many intersecting lines. From the x-axis (should be a big black line that moves left to right), move down four lines. Once you get to the fourth line, trace the line from left to right. Put some points at the y-value of -4 (for example (-1, -4)) if it helps you straighten the line.  

Some lines may be vertical and move up and down. Those lines have an x instead of a y (x=3, x= -12, etc.). Fortunately, these lines, both vertical and horizontal, are a lot easier to draw than other equations.
