I think 5.55 will travel in 3.7 seconds
Answer:

Step-by-step explanation:
In order to find the slope of this equation, we can convert it into slope-intercept form, where we can find the slope more easily.
Slope intercept form is usually in the form
, where m is the slope and b is the y-intercept.
Let's algebraically manipulate this problem so we solve for y.
<em>(Subtract 7x from both sides)</em>
<em>(Divide both sides by -2)</em>
<em>(Rearrange the equation</em>)
From here, we can now see our equation is
, in the form
. Since m is the slope, and
is m, our slope is
.

To find the angle x, you are given the triangle side lengths that are opposite and adjacent to the angle. The opposite side is 49 units long. The adjacent side is 24 units long. The trigonometric function that corresponds to the opposite and adjacent legs is tangent.
to find x: 
to find an angle using a trigonometric function we must use the inverse function.

The angle x, to the nearest tenth of a degree is 63.9 degrees.
(0,4) is the y intercept
