It says to solve the 9 problems. 3.) Is to build a triangle so that each edge has the same answers facing eachother. It's also says to record letters in your triangle from left to right. And the example of the answer needs to be this Ex answer; ABCDEFGHI. I just want to understand how we put the letter in order or solve it.

hi how are you doing today? if you ever need just tell me

step-by-step explanation:

3+x

step-by-step explanation:

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
