6x+5y=-15
5y=-15-6x
y=(-15-6x)/5
Answer:
She incorrectly multiplied 15 X 1/4
Step-by-step explanation:
The answer would be slope= -5/4
Hope this helps
Have a great day/night
Feel free to ask any questions
we know that
The formula to calculate the slope between two points is equal to

<u>Part a) Find the slope of line PQ</u>

substitute in the formula


Any line parallel to X-axis has slope equal to zero
so
the line PQ is parallel to the x-axis
therefore
<u>the answer Part a) is </u>

<u>Part b) Find the slope of line MN</u>

substitute in the formula


Anything divided by zero is undefined
m=undefined
therefore
<u>the answer Part b) is </u>
undefined
<u>Part c) How are the two lines related ? </u>
we know that
Any line perpendicular to X-axis has slope undefined
Because the term
will always be zero
so
<u>the answer Part c) is</u>
the lines are perpendicular
Step-by-step explanation:
First, You would solve what you can which would be the equation on the left Which will get you 4096. After that its just solving for P
4096=(4^p)^2
64=4^p (you would take the square root of 4096 to get 64)
Then, Since 64 is a perfect Cube root of 4, P will equal 3
