Answer:

Step-by-step explanation:
Hi there!
Slope-intercept form:
where
is the slope and
is the y-intercept (the value of y when x is 0)
<u>1) Determine the slope (</u><u><em>m</em></u><u>)</u>
where two given points are
and 
Plug in the given points (15,2.2) and (5,1.6):

Therefore, the slope of the line is
. Plug this into
:

<u>2) Determine the y-intercept (</u><u><em>b</em></u><u>)</u>

Plug in a given point and solve for b:

Therefore, the y-intercept is
. Plug this back into
:

I hope this helps!
The answer for this answer would be B. X is less than -10 so B would be the answer.
Here we are finding x, given the angle and adjacent side. To find x we will use the function cos as cos = a/h.
So let's do cos(35°) = 15cm / x
cos(35°) = 0.8 (1 dp)
x = 15 cm / cos(35°)
x = 18.3 cm (1 dp)
By knowing the volume of a triangle and that the triangle has all equal sides
Scalene and right, since:
There is a right angle
and scale means that there are no angles that are the same.
