Answer:
Slope is undefined
Step-by-step explanation:
Slope is calculated by
so now you put the points (-10,4) and (-10,8) into that.
Since both x values are the same you can tell that the line is a vertial line meaning the slope is undefined.
7x(√x - 7√7) Multiply √7x to "√x" and "-7√7" respectively:
√7x*√x - 7√7*√7x
First is to simplify: √7x² - 7√7²x
Extract the squares: x√7 - 7*7√x
Then, we simplify: x√7 - 49√x
After simplifying the equation, I got the answer x√7 - 49√x.
