Solve the proportional equation:

3/2= 6/n

what is the slope between (9,-1) and (-2,5)?

3/2=6/n. Cross multiply
3n=12. Divide both sides by 3
3/3n=12/3
n=4
Therefore n equals 4
Slope(m)=2nd y value minus 1st y value divided by 2nd x value minus the first x value
m=y2-y1/x2-x1
m=5-(-1)/-2-9
m=5+1/-2-9
m=6/-11
Thus the slope is -6/11
