A calculator lol?
Answer:

Step-by-step explanation:
Remember that the equation of the line is

in this case we have

that is because

180 degrees. in an equilateral triangle, each angle is 60 degrees
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
