A line has slope -3 and the y intercept is 7. what is the slope intercept form of the line?

y = -3x + 7

Step-by-step explanation:

m = slope

b = y intercept

eq:

i believe

step-by-step explanation:

from my conclusion c

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.
