Question
? Families of Lines Use a graphing device to graph the given family of lines in the same viewing rectangle. What do the lines have in common?$$y=-2 x+b \quad \text { for } b=0, \pm 1, \pm 3, \pm 6$$
Step 1
The equation is in the form of a straight line, y = mx + b, where m is the slope and b is the y-intercept. In this case, the slope is -2 and the y-intercept varies as b = 0, ±1, ±3, ±6. Show more…
