Answer:

(1.6+3.2)/(-1.5-2.1)= 4.8/-3.6= -2.4/1.8= -1.2/.9= -1 1/3 or -4/3

For this case we have that by definition, the slope of a line is given by:

[tex]m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}}[/tex]

We have as data that:

[tex](x_ {1}, y_ {1}) :( 2.1; -3.2)\\(x_ {2}, y_ {2}): (- 1.5; 1.6)[/tex]

Substituting the data:

[tex]m = \frac {1.6 - (- 3.2)} {- 1.5-2.1} = \frac {1.6 + 3.2} {- 3.6} = \frac {4.8} {- 3.6} = - 1.33[/tex]

Answer:

-1.33
