“write the equation for the line in slope-intercept form” y=-1x+3
y=4x+3
y=1/4+3
y=-4x+3

The equation is 4x + 3

the answer is a if my teacher taught me correct

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.
