Answer: Our required equation would be

Step-by-step explanation:

Since we have given that

y=30, when x = 6.

As there is direct proportion between x and y.

so, it becomes,

So, the equation connecting y and x would be

When we put the value of k, we get that

Hence, our required equation would be y=5x

A straight line has a slope of 2.08. Calculate the angle that the line makes with the x (horizontal) axis.

zubka84 [21]

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:

$y = mx + b$

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, $a = \tan^{-1}{m}$ .

In this question:

We have that $m = 2.08$ . So

$a = \tan^{-1}{2.08} = 64.3$

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