### Subject: Spanish

For the following ten sentences, use por or para as the fill-in-the-blank answer, and explain each choice (from an online tutoring site): 1.Necesito ir a la farmacia _________ comprar una medicina. 2.Voy a cambiar esta camisa _______ esta otra que está limpia para salir a la calle. 3.Necesito caminar dos kilómetros ________ hora si quiero llegar a la farmacia antes de que cierren. 4.Tengo que comprar un boleto y necesito ir _______ avión a México. 5.Voy a ir a México ________ ayudar a mi madre a cuidar de mi hermana. 6.Después de comprar la medicina, voy a ir a recogerte y vamos a ir a preparar las cosas _________ el viaje. 7.Es un buen plan ________ mantenernos ocupadas. 8.Malena, ¿le dijiste a tu mamá que viniste a mi casa ___ mi viaje? 9.Gracias por venir a mi casa ___ ayudarme a empacar. 10.Pero recuerda que voy a volver ____ el día 23 de junio.

Para means *for* a purpose or a thing. Por can a lot but a few uses we’ll see here are “by," “per," and “on”—*by* plane, *per* hour, *on* a thing or on a day. 1, 5, 7, and 9 use para with verbs—para comprar - to buy, etc. #2 por we could translate “with”--I’m going to exchange that shirt with that other one… 3 uses por to mean “per”—2 kilometers per hour In 4 por means “by”—as a means of doing something In 6 and 8 para still means “for,” but it’s *for* a thing rather than a verb. 10 we use “por” to say it’s on a certain day that I’ll return.

What is paraphrasing, and do I still need to use citations when I do this?

Paraphrasing is taking a sentence or an idea from someone else’s work, and putting it in your own words. You’ll have to make almost all the words different before it’s considered paraphrased. For example say I have the sentence "Being a country of rivers and floodplains with a high potential of aquatic resources, fish plays a very important role in the daily life of many people in Bangladesh.” A good paraphrase might be “Fish is central to the life of many residents of Bangladesh, since the country contains an extensive system of rivers and floodplains." Any time your paper borrows an idea from someone, you’ll include a citation. In the APA style, an in-text citation for my example would be (de Graaf and Latif, 2002).

What is the equation of the line described: through: (2, -4), parallel to y= -5/2x + 4?

So for the equation of a line we need two pieces of information--the slope, which we can also say is what direction it points, and the y-intercept, which is how far it's bumped up along the y axis. The way people sometimes write this equation is y = mx + b. X and y are the variables, so we need to find m (the slope) and b (the y-intercept). If this line is parallel to the other one, that means it points in the same direction, so it has the same slope. So our m is -5/2. y = -5/2x + b. Now we just need b. We know the line passes through (2, -4), so that's an x and y. If we plug them into our equation, we can find out what b has to be to fit that point. -4 = (-5/2)2 + b -4 = -5 + b *add 5 to both sides* b = 1 Now that we have m and b, let's make the full equation: y = -5/2x + 1
