Answer:

A

Step-by-step explanation:

The line passes through the points (-3,-7) and (9,1).

The slope of the line can be calculted using formula

[tex]\dfrac{y_2-y_1}{x_2-x_1}.[/tex]

Thus, the slope of the given line is

[tex]\dfrac{1-(-7)}{9-(-3)}=\dfrac{8}{12}=\dfrac{2}{3}.[/tex]

Answer:

A

Step-by-step explanation:

slope is given by the formula:

[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

We need 2 points to find a line's slope.

  • The first point is (-3,-7) hence x_1 = -3 & y_1 = -7.
  • The second point is (9,1) hence x_2 = 9 & y_2 = 1.

Plugging these into the slope formula, we will get the slope:

[tex]\frac{1--7}{9--3}\\=\frac{1+7}{9+3}\\=\frac{8}{12}\\=\frac{2}{3}[/tex]

correct answer is A
