graph the line.\n$y=-2x - 1$
graph the line.\n$y=-2x - 1$
Answer
Explanation:
Step1: Find the y - intercept
The equation is in the form (y = mx + b), where (b) is the y - intercept. For (y=-2x - 1), when (x = 0), (y=-1). So, plot the point ((0,-1)).
Step2: Find another point using the slope
The slope (m=-2=\frac{\Delta y}{\Delta x}). From the point ((0,-1)), if (\Delta x = 1), then (\Delta y=-2). So, the new point is ((0 + 1,-1-2)=(1,-3)). Plot the point ((1,-3)).
Step3: Draw the line
Connect the two points ((0,-1)) and ((1,-3)) with a straight line.
Answer:
Plot the points ((0,-1)) and ((1,-3)) and draw a straight line through them.
