Question

Indicate in standard form the equation of the line passing through the given point and having the given slope.

D(5, -2) m = 2/5

Answer 1

For the equation y = mx+c, m = slope.
Now, you have the slope, so it becomes
y= (2/5)x +c -(1)
Put (5, -2) into (1)
-2 = 2/5 ( 5) + c
-2 = 2 + c
c = -4

Can you rewrite the equation now?

Answer 2

i dont know how..

Answer 3

y = mx+c
What is m? what is c?

Answer 4

m=2/5 c=-4

Answer 5

i need to put it in this form.. _x_ _ y_____

Answer 6

y = mx+c
y = 2/5 (x) -4
Now, rearrange the terms... Multiply both sides by 5, what do you get?

Answer 7

5y=2-20

Answer 8

.

Answer 9

Oh.. You missed the x..
5y=2x-20
Now, subtract 5y from both sides, what do you get?

Answer 10

but,...

Answer 11

Yes?

Answer 12

i need to put it in this form.. _x_ _ y_____

Answer 13

-5y?

Answer 14

Do you need it in the form _x __y = _ or _x __y ___ = 0 ?

Answer 15

Yes, -5y from both sides

Answer 16

any form

Answer 17

Okay... -5y from both sides, what do you get?

Answer 18

5y=2x-20
5y - 5y = 2x - 20 - 5y

Answer 19

2x-5y=-20?

Answer 20

Nope...
5y - 5y = 2x - 20 - 5y
0 = 2x - 5y - 20
Got it?

Answer 21

yup:D thanks
