y= -1/2x-3
y= -7/3x-5
Slope intercept form is y=mx+b. M is the slope and B is the y-intercept.
I hope that this helps
One <em>correct answer</em> is:
Let <em>m </em>and <em>n </em>be lines that intersect line <em>a</em>. Let <em>m</em> be perpendicular to <em>a</em>. This means that all 4 of the angles formed by the intersection of <em>m</em> and <em>a</em> are 90°.
Let <em>n</em> be perpendicular to <em>a</em>. This means that all 4 of the angles formed by the intersection of <em>n </em>and <em>a</em> are also 90°.
Since all of the angles are congruent, this means that the same-side interior angles (between lines <em>m</em> and <em>n</em>) are congruent. If two same-side interior angles are congruent, then the lines are parallel.

We take GCF by factoring out the algebraic expression.
2x³ + 4x is factored out into 2x(x² + 2) and
−5x² − 10 is factored out into −5(x² + 2)
Therefore the common binomial factor is x² + 2
