Which equation represents the line that passes through the points (6 -3) and (-4 -9)
Answers
which is...
y2 - y1
m = -----------
x2 - x1
and since they already gave you two x and y coordinates this is really simple:) first of all you need to understand what is y2, y1, or x2, x1
taking the points (6,-3) i hope u understand that 6 is the x and -3 is the y. so knowing that information you always remember to use the information in the order that they gave it to you. i will add an extra link to help explain. Sooo then knowing that you plug it into the formula that I gave you earlier
so look at the next link that i made:)
so your slope is 6/5! or 1.2 as a decimal
hopefully you would know what an equation looks like but just in case this is it y = mx+b
so your equation looks like this y = 1.2x -3
where did i get the -3?
well look at first x and y coordinate thats your first y intercept:))
hope i helped!!.... and that this was right lol
let me know if it was correct thanks.

Hi Brainiac
7r= 10+5
7r= 15
Divide both sides by 7
7r/7= 15/7
r= 5/7
or the decimal will be r= 2.14

Answer:
49 1/8 minutes
Step-by-step explanation:
Jamie has 1/4 of the 26.2 mile distance to go, so must finish ...
(26.2 mi)/4 = 6.55 mi
The time in hours required to do that is found by dividing distance by speed:
time = distance/speed = (6.55 mi)/(8 mi/h) = 0.81875 h
In minutes, this is ...
(0.81875 h)×(60 min/h) = 49.125 min = 49 1/8 min
It will take Jamie 49 1/8 minutes to finish the race at her current speed.

y + 1/3 = (2/3)x
(3/2)*(y+1/3) = x
(3/2)y + 1/2 = x
f^-1(x) = (3/2)x + 1/2
This is the inverse you need to graph. You can plot this yourself, or use a graphing calculator.
The domain of f^-1(x) is all real numbers
The range of f^-1(x) is all real numbers
For the next 2, just plug in the values and solve:
f(2) = 1
f^-1(-19) = -28
