Step-by-step explanation:
Given equation:
To find the equation of line parallel to the line of the given equation and passes through point (-2,4).
Applying slope relationship between parallel lines.
where
and
are slopes of parallel lines.
For the given equation in the form
the slope
can be found by comparing
with standard form.
∴![m_2=3](/tpl/images/0417/6848/28cf4.png)
∴![m_1=3](/tpl/images/0417/6848/eb761.png)
The line passes through point (-2,4)
Using point slope form:
Where
and ![m=m_1=3](/tpl/images/0417/6848/150e6.png)
So,
Simplifying
Using distribution.
Subtracting 4 from both sides.
Thus the equation of line in standard form is given by:

Well it is a triangle so u have to multiply all the numbers but
u also have to add while doing it to first u multiply 20 and 12
then u add 15 to get blank that will be youre missing number
