Answer:
A trend line is a straight line that best represents the points on a scatterplot. The trend line may go through some points but need not go through them all. The trend line is used to show the pattern of the data. This trend line may show a positive trend or a negative trend.
Step-by-step explanation:
answer above
Answer:
m=1
Step-by-step explanation:
tttttttttttttt tttt
We have that
<span>Consider the graph of the line y = x – 4 and the point (−4, 2).
part 1)</span><span>The slope of a line parallel to the given line is
the slope m of the given line
y=x-4-----> y=(1)*x-4
is m=1
the answer Part 1) ism=1Part 2) </span><span>A point on the line parallel to the given line, passing through (−4, 2)
the slope m=1
y-y1=m*(x-x1)------> y-2=(1)*(x+4)-----> y=x+4+2------> y=x+6
the answer Part 2) isy=x+6part 3) </span><span>The slope of a line perpendicular to the given line is .
we know that
when two lines are </span>perpendicular
m1*m2=-1
m1=1
m2=-1
the answer part 3) ism=-1Part 4) <span>A point on the line perpendicular to the given line, passing through (−4, 2), is
</span>the slope m=-1
y-y1=m*(x-x1)------> y-2=(-1)*(x+4)-----> y=-x-4+2------> y=-x-2
<span>
the answer Part 4) isy=-x-2see the attached figure</span>
Step-by-step explanation:
A is in Quadrant I
D is in Quadrant III
