Please help ASAP Payton collected data to show the relationship between the number of hours he practices and the number of errors he makes when playing a new piece of music. The table shows his data. Which is the approximate slope of the line of best fit for the data? –5.5 –4.5 –2.0 –1.0

Option B.

Step-by-step explanation:

The general equation of best fit line is

where, a is the slope of best fit line and b is y-intercept.

Using graphing calculator a=-4.54762 and b=43.7143. So equation of best fit line is

Here,

Note: In alternate method, you can use the below formula to find slope.

Therefore, the correct option is B.

B: -4.5

Step-by-step explanation:

y ≈ -4.548x + 43.714 is the entire equation. So -4.548 or -4.5 is the slope.

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3

step-by-step explanation:

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!
