168.945/4

Hence answer = 33.79 km/hr

To find the distance between the two points, we must use the distance formula

⇒ Distance Formula ⇒ $\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}$

$(x_1,y_1): one_.point_.on_. the_.line$
$(x_2,y_2):another_.point_.on_.the_.line$

Now let's consider the information:

$(x_1,y_1): (-10,-9)$
$(x_2,y_2):(-1,-5)$

Let's solve:

$Distance_.between_.EG = \sqrt{(-5--9)^2+(-1--10)^2} =\sqrt{4^2+9^2}\\Distance_.between_.EG=\sqrt{16+81} \\Distance_.between_.EG =\sqrt{97} \\Distance_.between_.EG=9.85$

Thus by rounding to the nearest tenth

⇒ Answer: 9.9

Hope that helps!

Write the equation of the line.

kotykmax [81]

Answer:

y = 4

Step-by-step explanation:

Since the line in question is parallel to the x axis, we can tell that going from one end of the line to the other, x value changes, but y value always stays the same and equals 4.
