It is helpful to estimate quotients when the number is very big.
Step-by-step explanation:
For every increase in the x-value by 1,
the y-value decreases by -2.
(From 3 to 1 and from 1 to -1)
Hence, slope of line k
= Rise/Run = (-2)/1 = -2. (A)
Answer:
2y + 2x = 0
Step-by-step explanation:
First you have to find the slope of the line.
Parallel lines have same slope
2y = -2-2x
y=-1-1x, y=-1x-1
slope = -1
Use point slope formula
y-y=m(x-x)
y-(-9) = -1(x-9)
y+9 = -1(x-9)
y+9 = -1x+9
y = -x
y + x = 0
2y + 2x = 0
