Question

Identify the correct slope and y intercept of the equation 2x + 4y = 12.

A. slope = 2; y intercept at (0, 12)

B.slope = one half; y intercept at (0, 3)

C. slope = one half; y intercept at (0, 4)

D. slope = -one half; y intercept at (0, 3)


i think it's D but im not sure...

Answer 1

\[\implies 4y = -2x + 12\]
\[\implies y = \frac{-2x + 12}{4}\]
\[\implies y = -\frac 24x + \frac{12}{4}\]
\[\implies y = -\frac 12 x + 3\]
in short you're right

Answer 2

ok thank
