The diagram above, not drawn to scale,shows a triangle, ABC, with area 28units². Show workings. a) find the coordinates of C b) Find the equation is the line BC
A. (0,-6) plug in the area to the area formula for a triangle (A=1/2bh). so 28=1/2b(4) [since the height is 4]. divide by 4 (7=1/2b). multiply by 2/divide by 1/2 (14=b). the base equals 14 units long. B. y=2/3x+4 find the slope of the line (2/3) the y-intercept is 4
