Write the equation of the line in standard form that passes through (-1, 3) and (2, 9). }

y = 2x + 5

Step-by-step explanation:

(-1 , 3) & (2 , 9)

x₁ = -1  ; y₁ = 3    & x₂ = 2 ; y₂ = 9

m = 2 & (-1 , 3)

Equation of line:

y - y₁ = m(x - x₁)

y - 3 = 2(x - [-1])

y -3 = 2(x + 1)

y - 3 =2x +2

y = 2x + 2 + 3

y = 2x + 5

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
