Answer:

The angle that the line makes with x-axis of of 64.3º.

Step-by-step explanation:

Equation of a line, and angle with the x axis:

The equation of a line has the following format:

[tex]y = mx + b[/tex]

In which m is the slope.

The angle that the line makes with the x axis is given by the angle which has tangent m, that is, [tex]a = \tan^{-1}{m}[/tex].

In this question:

We have that [tex]m = 2.08[/tex]. So

[tex]a = \tan^{-1}{2.08} = 64.3[/tex]

The angle that the line makes with x-axis of of 64.3º.
