A.2
B.-2
C.1/2
D.1
E.-1


Sagot :

Answer:

D. 1

Step-by-step explanation:

Given points are: (5,8) and (6,9)

[tex]\implies x_1=5,\: x_2=6,\: y_1=8,\: y_2=9[/tex]

Formula for slope of a line is give as:

[tex]Slope \: of\: line =\frac{y_2-y_1}{x_2-x_1}[/tex]

Plugging in the values of [tex] x_1,\: x_2\: and\:y_1,\: y_2[/tex] in the above formula, we find:

[tex]Slope \: of\: line =\frac{9-8}{6-5}[/tex]

[tex]Slope \: of\: line =\frac{1}{1}[/tex]

[tex]Slope \: of\: line =1[/tex]
