Answer:
if you see the graph for x=-1
the y is equal -4
you can draw a straight line parallel y axes from point x=-1 it will cut the graph on y=-4
The graph shows a number line marking all numbers less that 10.
Choice a:
<span>c + 7 ≤ 3
</span><span>c ≤ 3-7
</span><span>c ≤ -4
Choice a is a wrong choice
Choice b:
</span><span>c - 3 > 1
</span><span>c > 1+3
</span><span>c > 4
Choice b is a wrong choice
Choice c:
</span><span>c - 7 < 3
</span><span>c < 3+7
</span><span>c < 10
Choice c is the correct choice</span>
If y=mx+b,

You can't differentiate a constant, so dy/dx=m.
D. Infinitely many because the lines will never Intersect which means there are infinitely solutions
The common multiple would be 2
