Find the perimeter of the triangle? what does 2 represent in the triangle?

6 + 5

Step-by-step explanation:

Since the triangle is isosceles then the 2 marked sides are congruent.

Using the rule of radicals

× ⇔

Thus perimeter (P) is the sum of the 3 sides

P = + 3 + + 3 +

  = 2 + 6 +

  = 2( ) + 6 +

  = 2 ( ×   ) + 6 +

  = 2(2 ) + 6 +

  = 4 + 6 +

  = 6 + 5

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
