yan [13]3 years ago
8 0
Answer:All these are equivalent, valid answers:

 y  <  -12

all real numbers less than  - 12:

( - ∞ , - 12)

{ y ∈ R | y < - 12}

Explanation:

1) Starting pointL inequality (1/2)y + 6 < 0

2) subtract 6 from both sides:

(1/2)y + 6 - 6 < 0 - 6

(1/2) y < - 6

3) multiply both sides by 2:

(2)(1/2)y < - (2) (6)

y  <  -12

4) That is all real numbers less than  - 12:

Equivalent to ( - ∞ , - 12) or { y ∈ R | y < - 12}

HELP PLEASE: Which is the equation of the graphed line written in
maksim [4K]

Answer:

x - y = 0

Step-by-step explanation:

Required

The graph equation

From the graph, we have:

(x_1,y_1) = (0,0)

(x_2,y_2) = (1,1)

The slope of the graph is:

m = \frac{y_2 - y_1}{x_2 - x_1}

m = \frac{1-0}{1-0}

m = \frac{1}{1}

m =1

So, the graph equation is:

y = m(x - x_1) + y_1

y = 1 * (x - 0) + 0

y = 1 * x

y = x

In standard form, we have:

x - y = 0
