Answer this by 4:20 EST and I will mark brainliest
Alexxandr [17]

Answer:

A

Step-by-step explanation:

Calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (6, a ) and (x₂, y₂ ) = (9, - 4 )

m = \frac{-4-a}{9-6} = \frac{-4-a}{3}

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

2x - 3y = 6 ( subtract 2x from both sides )

- 3y = - 2x + 6 ( divide through by - 3 )

y = \frac{2}{3} x - 2 ← in slope- intercept form

with slope m = \frac{2}{3}

Parallel lines have equal slopes , then

\frac{-4-a}{3} = \frac{2}{3} , so

- 4 - a = 2 ( add 4 to both sides )

-a = 6 ( multiply both sides by - 1 )

a = - 6 → A

Firdavs [7]

Answer:

subs with credentials get paid $87 per day. subs without credentials get paid $55 per day.

Step-by-step explanation:

let x be the cost subs with credential get paid per day and y be the cost subs without credential get paid per day

so we get

4x + 6y = 678 \\ 3x + 11y = 866

using simultaneous equation by substitution method you get x=87 and y=55
