Andrea Drew the Number line below. She said that 9/8 and 1 equal. Explain Error

It is incorrect. This is because 8/8 would equal 1, but it says there is one more than 8/8, which makes it 9/8. This means they are not equaled to each other.

1 = 1

9/8 = 1 1/8

Her error was that 1 and 9/8 are not equal. 9/8 is 1/8 larger than 1 is, and therefore can not be equivalent to 1.

your answer would be 12

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
