I know this isn't Spanish related but I need help with this math problem that I don't understand. I checked online and no places helped me.

How would you do this math problem?

(4,3)(x,7) slope=2

Thanks for the help,

You need to make a proportion based on the slope and two points. - espanol5555, Jan 2, 2011

(7-3)/(x-4)=2
2x-8=4
x=6

jesus, esta es la respuesta??? no me sorprende que siempre saques mis frases misteriosas para mi esto es chino total - 00494d19, Jan 2, 2011
Thanks Lorenzo9 - jolt, Jan 2, 2011
Suelo sólo escribir x=6, pero es un sitio instructivo. . .matematicás es mi primer idioma. :) - lorenzo9, Jan 2, 2011
jeje, es una buena manera de ponerlo, tu primer idioma, genial, pues no lo sabía, mucha gente de ciencias se interesan por los idiomas, seguro que jolt está encantado - 00494d19, Jan 2, 2011
jaja No me mires tampoco. Matematicas fue un puro suplicio para mi. Tengo más aptiud con lenguaje. - BellaMargarita, Jan 2, 2011
tiene razon. Me gusto matematicas! - espanol5555, Jan 2, 2011

(4,3)(x,7) slope=2

Rise over run = slope
Rise = Y2 - Y1 = 7 - 3
Run = X2 - X1 = x - 4
(7 - 3) / (x - 4) = 2
4 = 2x - 8
x = 6

Or what Lorenzo said.

By the way, at least I can learn a word here: what is slope? Is that a word or a term?

If it is a word, please let me know...I don't think I will understand if it is some kind of math term.

It is a proper English word, meaning pendiente in Spanish. In mathematics it means pendiente de la recta in Spanish, specifically how much of a change in the Y direction (up/down) there is for every change in the X direction (left/right).

... and since the Y changes from 3 to 7 (i.e. 4), the X must change by half (i.e. 2), so 4 should increasee to 6. Not difficult if you undderstand what a gradient is. - lazarus1907, Jan 2, 2011
Or to put it another way, since the slope is 2, the Y will change twice as much as the X. - KevinB, Jan 2, 2011

Slope is a word that can be used to describe a situation where alttude cha ges over distance. A roof has a slope. A ski run has a slope. - Leatha, Jan 2, 2011
Slope is change in y over change in x on the Cartesian co-ordinate system. It is very important for engineers and solving linear programming problems. - espanol5555, Jan 2, 2011
jeje, español, dont even bother, of course, lea, I knew that slope, great, I remember now - 00494d19, Jan 3, 2011

Normally this website has a policy to not do people's homework for them.

Of course, usually the requests are for Spanish homework.

You got exceedingly lucky on this one, having hit the people who knew the answer on a night when they were in a good mood.

This, I'm sure was a one time thing. Don't push it and ask for help on your math homework again.
