Hide Steps

Answer

Step 3: Use point-slope form: \(y - y_1 = m(x - x_1)\Rightarrow y - (-8) = -4(x - 2)\)

Steps

Step 1 ：Step 1: Find the slope: m = \(\frac{y_2 - y_1}{x_2 - x_1}\) = \(\frac{4 - (-8)}{-1 - 2}\)

Step 2 ：Step 2: Simplify the slope: m = \(\frac{12}{-3}\) = -4

Step 3 ：Step 3: Use point-slope form: \(y - y_1 = m(x - x_1)\Rightarrow y - (-8) = -4(x - 2)\)
