Firstly find the slope: $Slope = \frac{y_2 - y_1}{x_2 - x_1} \implies \frac{12}{8} = \frac{3}{2}$ Let y = mx + c Put any of the point in this to find c: Put y = -4 and x = -4 So: $-4 = \frac{3}{2}(-4) + c \implies c = -4 + 6 \implies \color{green}{c = 2}$ So this is the y coordinate of y intercept..
