The equation ofa line that passes throug (x1,y1) and has s slope of m is
y-y1=m(x-x1)
given
point is (-1,-3) and slope=4
y-(-3)=4(x-(-1)) or
y+3=4(x+1)
B is the answer

Answer:
A = 693
Step-by-step explanation:
The shape presented is a parallelogram, and the formula for this is:
A = bh
The "b," is the base (21) and the "h," is the height (33), so plug this in:
A = (21)(33)
A = 693
Answer: Height of tree = 26 ft
Make a triangle ABC with 40 degrees angle. The shadow is the base of the triangle equals 31 feet.
Base = AC = 31
Perpendicular = CB = ?
Hypotenuse = AB
Using trigonometric equation
tan 40 (deg) = CB / AC
CB = Tan 40 x AC
CB = 0.83909 x 31
CB = 26.011
Thus the height of the tree = 26 ft
