Write the equation of a line that is perpendicular to 2x + y - 1 = 0 and passes through the point (-1,-4)
(ASAP please)

Aline passes through the point (2, -4) and has a slope of 0, what is the equation of the line? plz fast

Look at arnold's attempt to solve the equation for b: 3b = 12 b = 3 · 12 b = 36 describe the mistake that arnold made.

In the figure below, ∠dec ≅ ∠dce, ∠b ≅ ∠f, and segment df is congruent to segment bd. point c is the point of intersection between segment ag and segment bd, while point e is the point of intersection between segment ag and segment df. the figure shows a polygon comprised of three triangles, abc, dec, and gfe. prove δabc ≅ δgfe.
