Pls ! determine the horizontal asymptote for the rational function.

a rational function is graphed in the first quadrant, and in the second and fourth quadrant is another piece of the graph. the graph approaches an imaginary horizontal line at y equals 1 and approaches an imaginary vertical line at x equals 2.

y = −2
y = 2
y = −1
y = 1

What is the next step in the given proof? choose the most logical approach. a. statement: m 1 + m 2 + 2(m 3) = 180° reason: angle addition b. statement: m 1 + m 3 = m 2 + m 3 reason: transitive property of equality c. statement: m 1 = m 2 reason: subtraction property of equality d. statement: m 1 + m 2 = m 2 + m 3 reason: substitution property of equality e. statement: 2(m 1) = m 2 + m 3 reason: substitution property of equality
