Complete the equation of the line whose slope is -2
and y-intercept is (0,3)(

y=-2x+3

Step-by-step explanation:

You have to make a linear equation, which is in the y=mx+b format

m, which stand for slope is given. m=-2

b, which stand for the y-intercept, is also given. b=3

Therefore: y=-2x+3

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.
