Answer:
The equation can be used to find m, the midpoint of the
two numbers is:
Step-by-step explanation:
Two numbers are 10 units away in different directions from their midpoint, m, on a number line.
Then, we can define the two numbers as:
The product of the numbers is -99. This can be written as:
Answer:
Step-by-step explanation:
Hi there!
Slope intercept form: where m is the slope of the line and b is the y-intercept (the value of y when the line crosses the y-axis)
<u>1) Find the slope (m)</u>
where the two given points are
and
Plug in the given points (2,8),and (8,2)
Therefore, the slope of the line is -1. Plug this into :
<u>2) Find the y-intercept (b)</u>
Plug in a given point and solve for b
Add 2 to both sides
Therefore, the y-intercept is 10. Plug this back into :
I hope this helps!
Answer:
Step-by-step explanation:
(a). 270° clockwise or 90° counterclockwise:
(x, y) --------> ( - y, x )
(b). 270° counterclockwise or 90° clockwise:
(x, y) ---------> ( y, - x )
