Answer:
M = (Y2 - Y1) / (X2 - X1)
Step-by-step explanation:
First, look at a graph of a line and find two points, 1 and 2. You can use any two points on a line. The slope will be the same between any two points on a straight line.
Note the X and Y value for each of the points.
Now we'll designate the X and Y value for points 1 and 2. We'll use subscripts to identify them in the slope formula.
Hope this helps!
Step-by-step explanation:
I don't see any numbers, so I just give you an example :
<u>1</u>1
every position in a number is worth 10 times the value of the position to its very right.
so, in e.g. 11
the left 1 is worth 10 times the value of the right 1.
y= -3/5x + 1/5
Explanation: First subtract
3x from both sides, and you should have 5y = −3 x +1
. You are almost there to slope-intercept form, the 5y needs to be just
y. Divide by 5 on both sides (Make sure you divide −3x AND 1 by 5!).
The answer is fully given in the picture below. Hope it helps!
Answer: The last paper has to be 99 over 100 to move the class average by 1 point
Step-by-step explanation:
total points on the 23 exams: 23*75 = 1725
-----
For 24 papers to average 76 points you need 24*76= 1824
---
Score on the final paper would have to be (1824-1725) = 99
