All sides are the same, hence, all three angles are the same, and each one of them is 60 degrees. Due to that:
7x + 4 = 60
7x = 56
x = 56/7 = 8
8y + 12 = 60
8y = 48
y = 48/8 = 6
The area is (BK) times (AK or CK).
If you have no numbers given, it's not possible to find the length of BK, or the actual number that represents the area.
Answer:
you divide -8y by both sides and you would so that means that y=-2.
Step-by-step explanation:

The y intercept is (0, -7)
<em><u>Solution:</u></em>
<em><u>Given equation is:</u></em>
y - 3 = 5(x - 2)
<em><u>Find the x intercept</u></em>
Substitute y = 0 in given equation

<em><u>Find the y intercept:</u></em>
Substitute x = 0 in given equation

Thus the y intercept is (0, -7)
