What’s the y-intercept of the line?
A.1
B.(0,1)
C.(0,-1/2)
D. 1/2

B.  (0,1)

Step-by-step explanation:

the y intercept is the (0,y) on the graph where the line intersects.

answerthe vertex form

step-by-step explanation:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
