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

Answer 1

-1

Answer 2

y = - 2x - 1

By inspection, you can see that the graph is a straight line

with a slope of -2, and its y-intercept is -1.

-- Place a point on the y-axis at y=-1, and another point at (1, -2).

-- Place your straightedge along both points, connect them, and

extend the line-segment as far in either direction as you like.
