Answer:
-3
Step-by-step explanation:
An increase in x-value from 9 to 10 is an increase of 1 unit. The slope of -7 tells you that the corresponding change in y will by -7 units:
v = 4 -7 = -3
The value of v is -3.
_____
<em>Alternate solutions</em>
You can see this easily on a graph, or you can use the equation of the line. We have a point and a slope, so the point-slope form is useful.
y = m(x -h) +k
y = -7(x -9) +4
For x=10, the value of y is ...
v = -7(10 -9) +4 = -7 +4
v = -3
50/5 is 10 so the rate of change is 10
If 2 lines are parallel then:
they determine a plane, that is they are coplanar. In this plane, they never intersect.
<span>A) they intersect at a single point : Not True, they never intersect.
</span><span>B) they are perpendicular: Not true, they are parallel...
</span><span>C) the are skew lines : Not true, "skew" is the opposite of "coplanar". 2 lines are skew means that they are not on the same plane. But we mentioned that 2 parallel lines are always on the same plane.
</span><span>D) they are coplanar: True
Answer: D</span>
