Question

CAN SOMEONE ANSWER THIS FOR 100 points!!!

Answer 1

y = - 25x + 800

Explanation:

the equation of a linear function in slope- intercept form is

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

calculate m using the slope formula

m =
`(y_(2)-y_(1) )/(x_(2)-x_(1) )`

with (x₁, y₁ ) = (6, 650 ) and (x₂, y₂ ) = (8, 600 )

m =
`(600-650)/(8-6)` =
`(-50)/(2)` = - 25 , then

y = - 25x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (6, 650 )

650 = - 25(6) + c = - 150 + c ( add 150 to both sides )

800 = c

y = - 25x + 800 ← linear equation
