I'll help Is this algebra?
Okay lets walk through this
All I need is the answer, there are 6 parts I will type the rest after this one
Y=-2/3x+400. (slope)m=-2/3 (Y-intercept)b=400 really simple
So here is part one Change the equation into slope-intercept form. Identify the slope and y-intercept of the equation. Be sure to show all of your work.
if you want to know how i got it well you have to take the equation 2x + 3y = 1,200 -2x---> 3y= -2x+1,200 now divide 3 by -2x and 1,200 you get---> y= -2/3x +400
Ok here is the second part
to find the slope and y-intercept use this y=mx+b (m is slope, b is y-intercept.) y= -2/3x(m) +400(b)
Describe how you would graph this line using the slope-intercept method. Be sure to write in complete sentences.
Well you would plot point (400,0) then use your slope -2/3 (rise over run theory) from point (400,0) go down 2 on the Y axis then to the right 3 points on the x axis. You should have cord (398,3) now draw the line by connecting the dots.
Now part 3: Write the equation in function notation. Explain what the graph of the function represents. Be sure to use complete sentences.
