graph the line with the equation $y = 2x - 1$.
graph the line with the equation $y = 2x - 1$.
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=2x - 1), when (x = 0), (y=-1). So the point ((0,-1)) is on the line.
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 another point is ((0 + 1,-1+2)=(1,1))
Step3: Plot the points and draw the line
Plot the points ((0,-1)) and ((1,1)) on the coordinate plane. Then draw a straight line passing through these two points.
Answer:
Plot the points ((0,-1)) and ((1,1)) and draw a straight line through them to graph (y = 2x-1)
