Answer:

Step-by-step explanation:
Slope Formula: 
Simply plug in 2 coordinates into the slope formula to find slope <em>m</em>:



Answer:
False, there are actually infinite solutions as these are parallel lines.
Step-by-step explanation:
Answer:

Step-by-step explanation:
Given




Required
Find x
The area is calculated as thus:

Substitute values




Multiply through by 2


Remove absolute sign

Add 6 to both sides

Divide by 3


<em>So, the coordinates are (-8, 11) or (12,11)</em>
Step-by-step explanation:
I think the answer for the 3) is S=(a×ha)÷2= (7×4.2)÷2= 29,4 ÷2=14.7
And for the 5) one im really not sure.
The factors of a number are all whole numbers that can be multipled to get that number.
1, 2, 4, 8, 16, 32, 64
