y₁
11
Second point coordinates
x₂
7
y₂
21
Result
Slope (m)
5
m = 10 / 2 = 5 / 1 = 5
Your function
The entered points belong to an increasing, linear function.
Equation: y = 5x - 14.
Hope i helped :)
I don’t really understand for question 11 to 13

To begin, we can simplify the expression's denominator by finding a common denominator between the denominators of the fractions in the denominator. To make them compatible, we can convert

into

:

Next, we can simplify:

Finally, to cancel the denominator within the denominator, we can multiply the whole expression by

, or 1:

The expression simplifies to

, or

as a mixed number.
I think its 200%
Best Of Luck!!!!
