She may not be able to use a graphing calculator on a test

winsteria · Answer

Thank you though

pawanyadav · Answer

y=-3/2x+3
=>y+3/2x=3
=> y/3+x/2=1
=>y/b+x/a=1
Here a=2 is x intercept

pawanyadav · Answer

And b=3 is y intercept

shadowlegendx · Answer

You donʻt even have to do what he did above, just graph it. Or use your head.

We know 3 is the y intercept, so that just means itʻs 3 units up from (0,0). 

Using our head, if the slope is -3, it will go down 3 units, and then to the right 2 units.

Rise over Run

If it goes down 3, and over 2, it will be at (2,0)

Crossing the x-axis at 2
