y=mx+b
m=slope
b=y-intercept.
1) We need to know the value of the slope (m):
Given two points (x₁,y₁) and (x₂,y₂) the slope of the line passes through these points will be:
m=(y₂-y₁)/(x₂-x₁)
We choose two points of this line:
(-1,-8)
(4,2)
The slope will be: m=(2+8)/(4+1)=10/5=2
2) we have to find the y-intercept (b) of this line:
we choose any point of this line: for example (4,2) and plug in this point in this equation:
y=mx+b
therefore:
2=2(4)+b
2=8+b
b=2-8
b=-6
3) we can already make up the equation:
Data:
m=2
b=-6
y=mx+b
y=2x-6
Answer: y=2x-6

The +30 represents the 30 gallons of gasoline at the beginning of Samantha's road trip.
As each mile, x, does by, 1/25 of a gallon is lost (because the van gets 25 miles per gallon). so you put a negative 1/25 in front of the x. Therefore, when Samantha has driven x miles,she will have y gallons of gas left.

5% as a decimal and fraction
1) To make 5% to decimal you have to divide 5% by 100. Percent means something out of 100.
⇒ 5% ÷ 100 = n
n = 0.05
5% as a decimal = 0.05

5% as a fraction
1) Percent is always out of 100 so 5% would be out of 100
⇒ 5% = 5/100
The fraction of 5% is 5/100
5/100 can be reduced
To reduce a fraction you have to divide by the greatest common factor
The greatest common factor of 5 and 100 is 5.
5 ÷ 5 = 1
100 ÷ 5 = 20
5/100 in simplest form would be 1/20

Answer:
90 degree
Step-by-step explanation:
We start with SWV as right angle and isosceles can be found to find W
SWV = 90 so we know as isosceles they all are 90 degree met with 45 degree at line of intersections.
We see a right angle at point S on SWT and make a right angle triangle at SWT, to find T angle equal to S=90 W=45 T=45
So SWT = SRT = SRW = TRV
The middle points with R in them are all 90 at point R
The others are 90 at point S on TSW (SWT) and on all outside perimeters for the larger triangles.
