How do you do y equals -2x-1?

Answer 1

-1

Answer 2

What do you mean by "how do you do"?

• Do you want the derivative of y with respect to x? That'd be -2
• Do you want the integral? That'd be -x2 - x + C
• Do you want to solve for x? That'd give you x = -(y + 1) / 2
• Do you want to plot it on a graph? You can do that by taking a piece of graph paper, drawing vertices at the points (0, -1) and (5, -11), lining up a ruler with them, and tracing the line that that they define.
• Do you want to know how to say it in English? That would be "y equals negative two x minus one"
• Do you need the slope of the line? That's -2

Please state your questions clearly. Things like "How do you do" can mean almost anything, and usually won't be answered.
