1. Write the equation of the line for the points (2,-1) and (-4,11).

Step-by-step explanation:

Slope-intercept form of an equation is written as , where is the slope and is the y-intercept.

The slope of a line that passes through the points and is . Using the coordinates and as given in the problem, we have slope of this line to be:

.

Now using this slope we've found and any point the line passes through, we can find the y-intercept of this equation:

Therefore, the equation of this line in slope-intercept form is .

456567546657689765432567890-9876543567890-987657890

step-by-step explanation:

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
