Q2. first, calculate the slope of line SF;you have two points, so just use the m formula. any line // to that will use the same slope, so you can write the equation y = mx + b using the m just obtained and b = -5

Q1. begin by observing that the line 4x+y=2 has slope -4; any perpendicular thereto will have slope-¼ (neg. reciprocal of other slope). so now you have YOUR m = -¼ and you can use Point Slope form to write the equation based on (5,-2) being on your line.
