Answer:
a dot in an equation means multiplication
Answer:
Y=-4x
Step-by-step explanation:
We know the slope is negative since the line decreases from left to right. Starting at 0,0 we go down 4 and to the right 1 to get to the next point. Therefore the slope is the change in y over the change in x or -4/1= -4. The y intercept is 0 since it crosses the y axis at 0,0. The equation of the line in slope intercept form is y= mx+b or y= -4x
The median would be the middle data point. Let’s list the points
25, 26, 31, 39, 32, 57
Put them in order from least to greatest
25, 26, 31, 32, 39, 57
There is an even amount of data so take the two center points and divide by 2
31 + 32 = 63
Divide by 2
31.5
There would be an average of 31.5 strokes
Idk what it is tbh i can’t with math
Well, function is already written in "function notation" though not explicitly which I assume is "function notation".
Explicit notation for this function is:

Hope this helps.
