telo118 [61]

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 $m=\dfrac{y_2-y_1}{x_2-x_1}$

Let $(x_1,y_1)$ = (3, -1)

Let $(x_2,y_2)$ = (5, 4)

$\implies m=\dfrac{4-(-1)}{5-3}=\dfrac52$

This is Spencer's method

Let $(x_1,y_1)$ = (5, 4)

Let $(x_2,y_2)$ = (3, -1)

$\implies m=\dfrac{-1-4}{3-5}=\dfrac52$

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:

$m=\dfrac{y_2-y_1}{x_1-x_2}$

where it should have been $m=\dfrac{y_2-y_1}{x_2-x_1}$

Answer:

$2x^6$

Step-by-step explanation:

First, we find the greatest common factor 50, 10 and 2.

It is 2.

Then, we find the greatest common factor of $x^{6},x^{7}$ and $x^{8}$ which is $x^{6}$ .

Thus, the greatest common factor is $2x^6$
