Write an equation for each line.

Step-by-step explanation:

1. orange line: y = 4

2. Green line:

(0, -1), (1, 0)

(0 + 1)/(1 - 0)= 1/1= 1

y + 1 = x - 0

y = x - 1

3. black line:

(0, 4), (2, 0)

(0 - 4)/( 2 - 0) = -4/2 = -2

y - 4 = -2(x - 0)

y - 4= -2x + 0

y = -2x + 4

4. blue line: x = -4

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.
