Answer:
x-intercept (-8,0)
y-intercept (0,2)
Step-by-step explanation:
To find the x-intercept, you set y equal to 0.
Like this:
-2(0)+x=2(0)-8
0 +x=0 -8
x= -8
So the x-intercept is (-8,0).
To find the y-intercept, you set x equal to 0.
Like this:
-2y+0=2y-8
-2y =2y-8
Subtract 2y on both sides
-4y=-8
Divide both sides by -4
y=2
So the y-intercept is (0,2)
Given:
Triangle DEF
To find:
The perimeter of triangle DEF.
Solution:
Coordinate of D = (-1, 1)
Coordinate of E = (2, 1)
Coordinate of F = (-1, 4)
Distance formula:

<u>Distance of DE:</u>
Here, 


d = 3 units
<u>Distance of EF:</u>
Here, 



d = 4.2 units
<u>Distance of FD:</u>
Here, 


d = 3 units
Perimeter of ΔDEF = DE + FE + FD
= 3 + 4.2 + 3
= 10.2 units
The perimeter of triangle DEF is 10.2 units.
Let a function be defined from A to B then f is said to be one to one function if every element of domain has its unique image in co- domain . In other words, if each separate elements of set A are mapped with separate of set B then such function is known as one to one function.
The correct answer is second one
Answer:

Step-by-step explanation:
For this I would find two friendly points like (60,10) and (70,30). Now we will plug in for the slope-intercept formula
.
So...

Now we plug in and solve...

So the slope will be 2.
