Answer:
The equation of the line through the points (-5, 2) and (-2, 6) is 
.
Step-by-step explanation:
The point-slope form of the equation of the line is defined by this formula:
(1)
Where:
- Independent variable.
- Dependent variable.
- Slope.
, 
- Coordinates of the first point.
In addition, the slope of the line can be determined in terms of two distinct points:
(2)
Where 
, 
are the coordinates of the second point.
If we know that 
, 
, 
and 
, then the equation of the line is:
The equation of the line through the points (-5, 2) and (-2, 6) is .
From the excel plotting, we see that the least square regression equation is given by:
m=(7.25-2.65)/(2009-1978)
m=0.15
thus the equation will be:
0.15(x-0)=y-2.65
y=0.15x-2.65
b] Using the equation we can approximate the hourly wage in 2025 as follows:
x=(2025-1978)=47
y=0.15(47)-2.65
y=7.05-2.65
y=4.4
The plot is as shown in the figure:
18 will go into 50 2.77777777778.

Two numbers that multiply to -225 and add to 16 and 25 and -9.
Answer:
A: 10.9
Step-by-step explanation: -2.3 is 2.3 away from zero then add the length from zero to the postive number which in this case is 8.6, therefore the equation is 2.3 + 8.6 = 10.9
