First we want to get the slope which we will get from this equation
3x + 9y = 8
Can you tell me what the slope of this line is?
i just need the steps and the answer. i already learned the material back in september, just need some refreshing for the exam i have next week.
Oh ok First get the slope.
Then find the derivative of x + ln x
Set the derivative equal to the slope and solve for x.
Plug the x into the original equation y = x + ln x to get y
Now you have your slope m and point (x,y)
Use point slope form
where x1 and y1 is your point
