Answer:
Step-by-step explanation:
Point-slope formula is represented by the equation . When knowing a point a line crosses through and its slope, you can write an equation in this form. Substitute the
,
, and
for real values.
The represents the slope of the line. Since we know the slope is -2, substitute -2 for
. The
and
represent the x and y values of the point the line passes through. Since the line passes through (4, -6), substitute 4 for
and -6 for
. This gives the following answer and equation:
To solve this problem you must apply the proccedure shown below:
1- The formula for calculate the area of this rectangle is:
Where is the length and
is the heigth.
2. Let's call identify the heigth with the variable .
3. If the length is longer than the heigth, you have:
4. Therefore, you can write the following polynomial expression:
5. If you know the value of the heigth, you can susbstitute it into the polynomial expression shown above and you will obtain the area.
Therefore, the answer is:
