y= -2/3x +400
Describe how you would graph this line using the slope-intercept method.

anonymous · Answer

It's best to start off with the two axis intercepts. You already know one just by reading this equation, the y-axis.

anonymous · Answer

The y axis is (0, 400)

anonymous · Answer

so the slope is rise over run and 400 is the y intercept.

anonymous · Answer

Yes, and solve for the x-axis by settings y = 0 = -2/3x + 400

anonymous · Answer

$$\frac{ 2 }{ 3 } x = 400$$

anonymous · Answer

So the x-axis is (600, 0)

anonymous · Answer

Connect your x-axis with your y-axis, and extend both ends of the line to the edge of your graph. You're done!

anonymous · Answer

3	Write the equation in function notation. Explain what the graph of the function represents. Be sure to use complete sentences.

anonymous · Answer

Functional notation means that you express y in terms a function of x.

anonymous · Answer

$$f(x) = -\frac{ 2 }{ 3 } x + 400$$

|dw:1435179760642:dw| start at 400 go down two over three
