First find the slope of this new line; it's the same as the slope of the "given line," which you unfortunately have not yet given. Let's call that slope "m."
Then, the equation in point-slope form of the new line is
y - (-1) = m(x - [-1]), or y+1 = m(x+1)
Please go back to the original question, obtain the slope of the "given line," and substitute that value for m in y+1 = m(x+1).
B=area of the base and 12cm
H=height and 9cm
Volume= 216cm
