Answer: D. (-4, -2)
<u>Step-by-step explanation:</u>
Rotating 180° about the origin means the signs for the x- and y-values are opposite.
(x, y) → (-x, -y)
(4, 2) → (-4, -2)
If you use slope-intercept form, Y =mx+b
m is equal to the slope,
and b is the y intercept.
Y= (1/2)x+ (-1)
or
Y = (1/2)x-1
We have to make an equation: a number increased by 10 is 114.
An equation is:
x + 10 = 114
x = 114 - 10
x = 104.
1 pound= $0.50
10 pounds= $5.00
