Question

the characterizing property for each family of lines. Es 11.9 • (b) ar+By = 24 (d) = 4x + b (0) kx + kyrka (h) m(x + 2) = y - 1 (i) x=a (i) = tan 50° + b

Answer 1

Exercise e)

y = mx + 5

Then characterizing property is

y = 5/1

when x= 0

So then y-intercept is= (0,5/1)= (0,5)

f) kx + ky = k^2

Divide all this system by k,

then it results

(kx + ky )/k = k^2/k

then

x + y = k

Characterizing property is

x-intercept= (k, 0)

y-intercept= (0,k )
