Question

Point slope form with these points: (10, 5) and (12, 12)

Answer 1

I need an equation ;)

Answer 2

i think the slope of the line between the opoints is 7/2, as it is \[ \frac{change in y}{change in x} \]

Answer 3

so then you do y-5 = (7/2)(x-10)
2y-10=7x-70
2y-7x+60=0

Answer 4

yeah \(\frac{12-5}{12-10}\)

Answer 5

So, the equation is: 2y - 7x + 60 = 0

Answer 6

equation is usually expressed in this form y=kx+b

Answer 7

yes, or you can write it as \[y = \frac{7}{2}*x - 60\]

Answer 8

that is the equation in the form tomas said, either one is ok

Answer 9

you forgot to divide 60 by 2

Answer 10

\[y = \frac{7}{2}*x - 30\]

Answer 11

Okay. Thanks Tomas.A!!! :)

Answer 12

point slope? is that the point slope form.... i thought that was intercept slope form... i'm lost

Answer 13

i thinks it's same but im not sure since i didn't learn maths in english

Answer 14

point slope => y2-y1=m (x2-x1)

Answer 15

so she is asked to find point slope which is m and then she also asked for equation?

Answer 16

(10, 5) and (12, 12)
m=(12-5)/(12-10)
m=7/2


point slope form of equation of line on which the 2 points lie
(y-5)=(7/2) * (x-10)

Answer 17

(y-5)=(7/2) * (x-10)
y-5=(7/2)x - (7/2 * 10)
y-5=(7/2)x - 7*5
y=7/2x - 30

Answer 18

yeah 08bkrishna wrote like that

Answer 19

point slope form and intercept slope form are quite confusing, i normally go by y=mx+c but i only recently learned the difference in the 2 equation forms

Answer 20

So, what is the equation! :)

Answer 21

point slope form of equation of line on which the 2 points lie
(y-5)=(7/2) * (x-10)



if you keep simplifying it down, you'll result with the intercept slope form.

Answer 22

that's the final answer
\[y = \frac{7}{2}x - 30\]

Answer 23

the final answer is an intercept slope form... i believe the question was clearly asking for point slope, not intercept slope http://www.purplemath.com/modules/strtlneq2.htm

Answer 24

the point slope from isn't a simplified equation, if you go ahead to simplify it, you'll end up with the intercept slope form, that's the confusing part as to whether you should keep solving it but once u have the point slope form and that's what is being required of, stop there
