(2,-1)(8,4)
slope = (4-(-1) / (8-2) = (4 + 1)/6 = 5/6
y - y1 = m(x - x1)
(8,4)...x1 = 8 and y1 = 4
slope(m) = 5/6
now we sub
y - 4 = 5/6(x - 8) <==point-slope form
y - 4 = 5/6x - 20/3
y = 5/6x - 20/3 + 4
y = 5/6x -20/3 + 12/3
y = 5/6x - 8/3
-5/6x + y = - 8/3...multiply by -6
5x - 6y = 16 <==standard form
3x+2=6 x=4/3 you can use x as a variable to represent the unknown number
Answer:
-5x+3 OR 5x-3
Step-by-step explanation:
You find the inverse by replacing the x with the y, and solving for y. Doing this actually gives you -5x+3 but in this case, the closest answer would be 5x-3.
UPDATE: -5x + 3 can be written as 3 - 5x lol
