2 = Slope
8 = y intercept
y=Mx+B
M will always be slope
B will be your y intercept
Answer:
the median is $1.60 greater than the mean
Concurrent . Point of concurrency
First find the slope of the line that passes through (4,-1) and (-2,3) by calculating "change in y" / "change in x"
So slope = -4/6 = -2/3
Remember the format y = mx + b?
So pick any of the two coordinates (I'll use (4,-1)) and sub in what you can.
-1 = -2/3(4) + b
Solve for b and you'll get 1.66666.... aka 1 2/3
So the equation is y = -2/3x + 5/3
Now for the next question.
So 5/2.5 = y/10
cross multiply and simplify and you'll get y = 20
Answer:
The function has been flipped due to the negative in front.
The function has been shifted 17 units to the left.
The function has been shifted 4.3 units down.
Step-by-step explanation:
When functions are transformed there are a few simple rules:
- Adding/subtracting inside the parenthesis to the input shifts the function left(+) and right(-).
- Adding/subtracting outside the parenthesis to the output shifts the function up(+) and down(-).
- Multiplying the function by a number less than 1 compresses it towards the x-axis.
- Multiplying the function by a number greater than 1 stretches it away from the x-axis.
- Multiplying by a negative flips the graph.
