Answer:
Step-by-step explanation:
<em>y=mx+b</em>
<em>b is where the line touches the y-intercept</em>
<em>mx is the slope...rise over run (positive slope) OR fall over crawl (negative slope)</em>
<em />
b= 8
mx= -3/2
y= -3/2x+8
bear in mind that, direct proportional equations have a y-intercept.
for y = kx, is pretty much y = kx + 0, where 0 = y-intercept.
and the "k" constant of proportionality, is pretty much just its slope.
