i made it y=-3/2 x +11.5
but i think its wrong help
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!!
