Which equation is represented by the graph below?

 Option 3 is correct. i.e.,

Step-by-step explanation:

We are given with a line on proper graph.

So, we find the equation of line by using Two-Point form of line.

Two-Point Form of line states,

if a line passes through 2 point say , then equation of line is,

first we find 2 points from graph.

Intersecting points of line with x x-axis and y-axis are (4,0) and (0,2)

so, applying Two-Point form we get

The equation of line is

Therefore, Option 3 is correct.

step-by-step explanation:

double number line is not a standard concept, so it must have been defined in your textbook. assume top line is numerator.

see explanation

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
