Answer:
Step-by-step explanation:
the slope-International cept frome y= mx + b was where m is the slope and b y-intercept
y=mx +b
m= -2/5
b=2
slope is :2/5
y-intercept is :2
x. y
0. 2
1 8/5
6, 12, 18 (counting by 6)
8, 16, 24 (counting by 8)
For this case we have:
To begin we must graph
, for this:
We do
, then:

So, we have the point 
We do
, then:


So, we have the point
We place both points in a coordinate plane and graph the line. Now, we must find the shaded region that identifies the inequality 
We must replace any point located to the left or to the right of the line. If the inequality is met, then the shaded region will be on the respective side.
We substitute the point

The inequality is met, then the shaded region is to the right of the line.

Answer: It should be the third one
Step-by-step explanation:
Answer:
X=50°
Step-by-step explanation:
Let, the fourth angle in the quadrilateral be ∠A
The sum of all the four angles of the quadrilateral is 360°
So 40° + 110°+80°+∠A=360°
230°+∠A=360°
∠A=360°-230°
∠A=130°
The fourth angle of the quadrilateral is 130°
The angle A and X are the angles on a straight line
The sum of the angles on a straight line is 180°
so, ∠A+∠X=180°
130°+∠X=180°
∠X=180°-130°
X=50°
