HELP COLLEGE ALGEBRA

Answer 1

Answer:

1) $\frac{-8}{11}$  

2) $1.276$

3) $\frac{3}{4}$

4) $0$

Step-by-step explanation:

The slope formula of the line that pass across two points P1(x1,y1) and P2(x2,y2) is:

$\frac{y2 - y1}{x2-x1} = slope$

You can use this formula to solve all the four points:

1)

$\frac{6- -2}{-9 - 2} = \frac{-8}{11}$

2)

$\frac{- 9.1 - 0.6}{-9.5 - - 1.9} = \frac{97}{76} =(Rounded)= 1.276$

3)

$\frac{2-5}{-2 -2} = \frac{3}{4}$

4)

$\frac{4-4}{-9 --4} = \frac{0}{-5} = 0$
