Answer:
a) equation: y = mx + b y = - x -5
b) equation: y = x - 5
Step-by-step explanation:
x + y = 3 i.e. y = - x + 3
slope(m) = - 1
a) parallel line: slope (m') = -1
pass (3 , - 8) y intercept (b) = y - mx = -8 - (-1)x3 = -8 + 3 = -5
equation: y = mx + b y = - x -5
b) perpendicular line slope = - 1/m = 1
pass (4 , - 1) y intercept (b) = - 1 - (1 x 4) = - 5
equation: y = x - 5
