Answer:
r = 3.
Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:

In which m is the slope.
Finding the slope of a line, given two points:
When we are given two points of a line, the slope of the line is given by the change in y divided by the change in x.
Points (4,r), (r,3)
Change in y: 3 - r
Change in x: r - 4
Slope is 0, so:



The value is r = 3.
Answer:
B..-10
Step-by-step explanation:
this isn't wrong I promise!
7n - 2 - (3n - 9 - 5)
= 7n - 2 - (3n - 14)
= 7n - 2 - 3n + 14
= 4n + 12
Hope it helped!
Answer:
Step 3
Step-by-step explanation:
When you are solving such problems requiring so many PEMDAS rules and attention span, it can be easy to make silly mistakes. Here, Venessa divided 12 by 4 and got 4. It is actually 3. Make sure to do all your work with organization and neatness, and check your work again for any mistakes. Hope this helps!
