Quick answer A <<<<

All horizontal lines have an equation of
y = k where k is a number. k is the y intercept.
Here are a few lines drawn for you.

y = 3
y = 1
y = - 1
y = - 2

In y = ax + b the term ax disappeared. The graph shows that x is not zero. It has many values. So the m must be zero.

Answer:

#1: -2 ≤ y ≤ ∞

#2: -2 ≤ x ≤ 2

#3: -4 ≤ y ≤ 3

#4: -5 ≤ y ≤ ∞

#5: 0 ≤ x ≤ ∞

Step-by-step explanation:

To do these, you must understand what range and domain are:

Range: all the values that y can be

Domain: all the values that x can be

#1: It's asking for range, so look at the posible y values. The smallest y value is -2, and the largest is actually infinity. So, the range is: -2 ≤ y ≤ ∞.

#2: It's asking for domain, so look at the possible x values. The smallest is -2 and the largest is 2, so: -2 ≤ x ≤ 2.

#3: Again, it's asking for range, so look at the possible y values. The smallest is -4, and the largest is 3, so: -4 ≤ y ≤ 3.

#4: It's asking for range. The smallest value is -5, and the largest goes to infinity (from the arrows), so: -5 ≤ y ≤ ∞.

#5: It's asking for domain. The smallest x value is 0, and it goes to infinity. So: 0 ≤ x ≤ ∞.

The sum of three consecutive even integers is -78, what are the integers ?

Digiron [165]

First, you need to analize and understand the problem, then you must choose and strategy. There is a wide variety of strategies to solve a mathematical problem, in this case, you can use the following, which is based on the information given above:
1. You have that the sum of three consecutive even integers is $-78$ , therefore, you can given the variable $x
$ to the first integer, the second even integer is $x+2$ and the third one is $x+4
$ .
2. Calculate x:
 $x+(x+2)+(x+4)=-78$ 
 $3x+6=-78$
 $x=-28
$ 
 $x+2=-28+2=-26
$ 
 $x+4=-28+4=-24
$ 
Therefore, the answer is: $-28,-26,-24
$
