Answer:
line K: y = -1.25 X + 3.5
function line J: y = 0.8 X + 6.625
Step-by-step explanation:
slope of line m: Sm = (2-(-1)) / (5 - (-3)) = 3/8
line n // line m: slope N = Slope M
function line n : f(x) = 3/8 X + b
∴ 5 = 3/8 x 4 + b (y intercept of line N)
b = 5 - 3/2 = 7/2
fuction of line K: y=mx + b y= (6 - 3.5) / (-2 - 0) X + 3.5
line K: y = -2.5/2 * X + 3.5 = (-5/4) * X + 3.5
line J perpendicular to line K, so slope of line J equals to negative reciprocal of line K : 4/5
fuction of line J: y = 4/5 * X + B
6 = 4/5 * (-2) + b
b= 6- (- 8/5) =6+5/8
function line J: y = 4/5 * X + 6 5/8
