Answer:
5y + 15
Step-by-step explanation:
8y - 6y = 2y + 3y = 5y
13 + 2 = 15
Answer:
Spencer and Abigail are correct
Lauren is incorrect
Step-by-step explanation:
Spencer and Abigail are correct
Slope = change in y ÷ change in x
Or 
Let
= (3, -1)
Let
= (5, 4)

This is Spencer's method
Let
= (5, 4)
Let
= (3, -1)

This is Abigail's method
It doesn't matter which point you label as point 1 and point 2, as long as you carry out the slope calculation correctly.
Lauren's calculation is wrong as she calculated her slope as:
where it should have been 
Answer:
the last MNO and PQR is the correct answer
Answer:
K'= (-2, 4)
Step-by-step explanation:
First we are going to rotate our point 270° counterclockwise.
The rule for a 270° counterclockwise rotation is
, which means that we just need to interchange the coordinates of the point and change the sign of the x-coordinate:




Now, to shift the point 3 units down, we just need to subtract 3 units from the new y-coordinate of our resulting point form the previous procedure:



We can conclude that the coordinates of K' are (-2, 4)
Answer:
The equivalent ratios are:
s = \frac{LA}{r}s=
r
LA
r = \frac{LA}{s}r=
s
LA
The formula LA = rsLA=rs is given
In order to determine the equivalent ratios, make r the subject of the formula and s the subject of the formula in the above equation
To make s, the subject of the equation, divide both sides of the equation by r
s = \frac{LA}{r}s=
r
LA
To make r, the subject of the equation, divide both sides of the equation by s
r = \frac{LA}{s}r=
s
LA
