Answer:
-3/2
Explanation:
We need to get the line into
y=mx+b
Where m is the slope, and b is the y intercept
To do this, we need to isolate y
Subtract 3x from both sides
3x+2y=4
2y= -3x+4
Divide both sides by 2
y= -3/2x+2
Now it is
y=mx+b
And we can determine the slope.
y=-3/2x+2
Since -3/2 is being multiplied by x, it is the slope
Slope: -3/2
Hope this helps! :)
