1. which set of ordered pairs in the form of (x, y) does not represent a function of x?
a. (1, 1.5), (2, -1.5), (3, 1.5), (4, 1.5)
b. (0, 1.5), (3, 2.5), (1, 3.3), (1, 4.5)
c. (1, 1.5), (-1, 1.5), (2, 2.5), (-2, 2.5)
d. (1, 1.5), (-1, -1.5), (2, 2.5), (-2, 2.5)

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
