Use the double intercept approach to find the graph of –1 = –y + x

option: D

Step-by-step explanation:

The double intercept form of a line is given by :

.

where A is x-intercept of a graph and B is y-intercept of a graph.

we are here given a equation of a line as:

which could also be written in a double intercept form as:

now the graph of the double intercept form passes through  points (A,0) and (0,B).

so, the graph here passes through (-1,0) and (0,1).

Hence option D is correct.

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

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
