Answer:
use 2 defined points.
Lets use: (-3,0) and (0,3)
The equation is written as y = mx+b, where m is the slope and is the y-intercept
Slope - change in y / change in x:
Slope = (3 -0) /(0- -3) = 3/3 = 1
b is the y-intercept which is the y value when x is o, which is one of the points (0,3) so b = 3
The equation becomes y = x +3
Kala call lasted for 0.36 minutes
<em><u>Solution:</u></em>
Given that Kala purchased a prepaid phone card for $15
Long distance calls cost $12 a minute using this card.
If the remaining credit on her card is $10.68
To find: Number of minutes her call lasted
Let "x" be the number of minutes her call lasted
Cost of 1 minute = $ 12
Total balance = $15
Remaining balance = $ 10.68
So we can frame a equation as:
Total balance = Remaining balance + Cost of 1 minute x number of minutes her call lasted

So her call lasted for 0.36 minutes
-73.35. You have to use the distributive property and multiply -9 x 8.15
