I believe your equation is:
.
Start by manipulating the equation to make it look like the "slope-intercept" form of a line:
y = mx + b
where
m is the slope
b is the y-intercept at (0,b)
.
Start by multiplying both sides by 4:
Now, subtract 3x from both sides:
Finally, divide both sides by 8:
.
From the above, we now have:
m (slope) = -3/8
b (y-intercept) = -3/2
