Marissa subtracted a negative number from a positive number. Her result was negative. Is that reasonable? Explain.
s2008m [1.1K]
No. If you subtract a negative from a positive number its equivalent to adding the inverse of that negative number. If you add a negative to a positive number It is equivalent to subtracting from that positive number.

Answer:

y = 4x - 3\\Slope \ m_1 = 4

EQUATION OF LINE PERPENDICULAR

Lines \ are \  perpendicular => m_1 \cdot m_2 = -1\\

slope, m_2 = \frac{-1}{4}

equation \ of \ the\ line \ passing \ through \ (-2, 2) \ slope ,m_2 :\\(y - y_2) =m_2(x - x_2)\\ (y - 2) = \frac{-1}{4} (x -(-2))\\\\y - 2 = \frac{-1}{4} (x +2)\\\\y = \frac{-1}{4}x - \frac{1}{2}  + 2\\\\y = \frac{-1}{4}x + \frac{3}{2}

EQUATION OF LINE PARALLEL

Lines \ are \ parallel => m_1 \cdot m_3 = 1\\slope, m_3 = \frac{1}{4}Equation \ of \ the \ line \ through \ (-2, 2) \ and \ slope, m_3:\\(y - y_3) =m_3(x - x_3)\\\\(y-2) = \frac{1}{4} (x - (-2))\\\\y-2 = \frac{1}{4}(x+2)\\\\y = \frac{1}{4}x + \frac{1}{2} +2\\\\y = \frac{1}{4}x + \frac{5}{2}
