Answer:
y = 2x + 1
Step-by-step explanation:
Use slope-intercept form ( y = mx + b ) where m is the slope ( rise over run ) and the y-intercept is 1 because where x = 0, y =1. You can either use rise over run to solve the slope or plug in an x and y value on the line and solve algebriacally.
Rise Over Run:
Take two values on the line, for example, (0,1) and (1,3) y is the rise and x is the run, so write each one with y over x in fraction form.
(0,1) = [tex]\frac{1}{0}[/tex] (1,3) = [tex]\frac{3}{1}[/tex] then subtract the second value from the first
[tex]\frac{3}{1}[/tex] - [tex]\frac{1}{0}[/tex] = [tex]\frac{2}{1}[/tex] which simplifies to 2. So the slope is 2.
Algebra:
plug a coordinate on the line into the equation y =mx + 1. For example (1,3)
3 = m(1) + 1 anything multiplied by 1 is itself so we can cancel out the 1 in the equation
3 = m + 1 subtract 1 from both sides
-1 -1
2 = m each method shows the slope is 2 so now we can put it together into the answer, y = 2x + 1
The equation of the line shown in table is y=2x+1.
What is equation?Equation is relationship between two or more variables that are expressed in equal to form. Equation of two variables look like ax+by=c. It is of many types like linear equation, quadratic equation, cubic equation, etc.
How to form equation?We have been given a line and we have to form equation of that line. First of all we have to take two points and then we will be able to form that equation.
We have taken (0,1),(1,3). The equation is formed under:
y-1=(3-1)/(1-0)*(x-0)
y-1=2x
y=2x+1
Hence the equation of the line is y=2x+1.

Answers
9514 1404 393
Answer:
about 106.5 units
Step-by-step explanation:
The length of each side is found using the distance formula:
d = √((x2-x1)^2 +(y2-y1)^2)
For example, the length of side AB is ...
d = √((9 -2)^2 +(1 -3)^2) = √(7^2 +(-2)^2) = √53 ≈ 7.28
The other side lengths are calculated the same way. The sum of side lengths of the given triangle is ...
AB +BC +CA = 7.28 +13.34 +14.87 = 35.49
__
Multiplying each coordinate by 3 effectively dilates the triangle by a factor of 3 about the origin. That increases the perimeter by a factor of 3, so it is ...
3(35.49) ≈ 106.5 . . . . units

Answer: a= 144. b= 67
Step-by-step explanation:
Angle b and the angle of measure 113 are same side interior angles which sum to 180 (When 2 parallel lines are cut by a transversal, special angles are formed)
113+b=180. Subtract 113 from both sides.
b= 67 degrees
Now that you have b, the interior angles of four sided figures sum to 360.
a+113+67+36=360. Combine like terms.
a+216=360. Subtract 216 from both sides.
a= 144 degrees
