Question

Anyone can help me with any of these : http://media.ccsdde.net/aventa/Geometry/GEOMx-HS-A09/a/unit03/resources/docs/WritingEquations_WritingAssignment.pdf

Answer 1

do you have an idea?

Answer 2

let me give you a hint.. pick 2 points

Answer 3

hmm you there @guccimayne ?

Answer 4

HUh?

Answer 5

give me two points on the line

Answer 6

name two points...hint..x-intercept and y-intercept

Answer 7

(3,-3)

Answer 8

(0,-2)

Answer 9

(-3,-1)

Answer 10

im not that stupid i no what points are .

Answer 11

well that's good...let's use (0,-2) and (3,-3) and you said huh so i rephrased the question

let's use the equation \[\huge y - y_1 = \frac{y_2 - y_1}{x_2 - x_1} (x - x_1)\]
you're familiar with that right? two-point form?

Answer 12

yeah because you where like do you have any idea ... ill give you a hint..
acting like im stupid .

Answer 13

i was only asking if you have an idea so i can start from where you are getting confused...i wouldnt want to blindly solve this not knowing where you're getting confused right ^_^

Answer 14

okay just making sure

Answer 15

do i just pick two point from the graph and write is at equastion and that would be the answer?

Answer 16

you pick two points then you substitute the values nto the equation i said above \[y - y_1 = \frac{y_2 - y_1}{x_2 - x_1} (x-x_1)\]
we picked (0,-2) and (3,-3)
so if we substitute we get
\[y - (-2) = \frac{-3 - (-2)}{3-0} (x - 0)\]
then we simplify
\[y + 2 = \frac{-5}{3} x\]
then we change it into the form y = mx + b so we'll get
\[y = -\frac53 x - 2\]
was that clear?

Answer 17

i may have said some unclear steps..if so please let me know :)
