Where represents the number of days.
represents the number of likes she got.
To model the equation using Kyle's data we find the slope using the given coordinate.
Let us say and
Slope formula ,
Plug in the above points now, we get
Now we use the point-slope formula,
Plugging the corresponding values.
Thus option is B is the correct answer.
Answer:
Step-by-step explanation:
We have the two functions:
And we want to find (f-g)(x).
(f-g)(x) is equivalent to f(x)-g(x).
Therefore:
Simplify:
Therefore:
You can find the slope either by just looking at the line or using the slope formula.
#1: The slope formula is:
Find two points and plug it into the formula
I will use (0, 2) and (1, -1)
(0, 2) = (x₁, y₁)
(1, -1) = (x₂, y₂)
[two negatives cancel each other out and become positive]
m = -3
#2: To find the slope without having to do the work, you use this:
Rise is the number of units you go up(+) or down(-) from each point
Run is the number of units you go to the right from each point
If we start at a defined/obvious point, like (0, 2), find the next point and see how many units it goes up or down and to the right. The next point is (1, -1), so from each point, you go down 3 units and to the right 1 unit. So your slope is -3/1 or -3. You can make sure the slope is right by looking at another point.
