graph the line.\n$y=-3x - 1$
graph the line.\n$y=-3x - 1$
Answer
Explanation:
Step1: Find the y - intercept
The equation is in slope - intercept form (y = mx + b), where (b) is the y - intercept. For (y=-3x - 1), when (x = 0), (y=-1). So one point is ((0,-1)).
Step2: Find another point using the slope
The slope (m=-3=\frac{\Delta y}{\Delta x}). From the point ((0,-1)), if (\Delta x = 1), then (\Delta y=-3). So another point is ((0 + 1,-1-3)=(1,-4)).
Step3: Plot the points and draw the line
Plot the points ((0,-1)) and ((1,-4)) on the coordinate plane. Then draw a straight line passing through these two points.
Answer:
Plot the points ((0,-1)) and ((1,-4)) and draw a line through them.
