2x+3y=-9
slope formula :y= mx+b
m is the slope. b is the y- intercept.
Need to change 2x+3y=-9 into slope formula
3y= -2x-9
Divide by 3
y=-2/3x-3
Now Graphing :
1. Do the y- intercept first and then the slope.
2. Put a dot on the y-axis for -3
3. Then the slope.
4. Count down 2 from -3.
5. You will go down to -5.
6. Go across three times. Put a dot .
The line will be straight.
That's it .
