If that be the case, then we will use the same slope as:

$\displaystyle y=-\frac{3}{2}x+\frac{11}{2}$ which is $\displaystyle -\frac{3}{2}$

We need to find the y-intercept. Use the slope-intercept form of the linear equation and use the point given (5, 4).

$\displaystyle y=mx+b$

$\displaystyle 4=-\frac{3}{2}(5)+b$

$\displaystyle 4=-\frac{15}{2}+b$

$\displaystyle \frac{23}{2}=b$

Substituting back into y=mx+b, we have

$\displaystyle y=-\frac{3}{2}x+\frac{23}{2}$

And your answer was right!!(Clapping)
