Answer

Point slope $y-3=\frac{3}{2}(x+1)$ Slope intercept form $y=\frac{2}{2}x+\frac{9}{2}$

Work Step by Step

To be parallel the equation must have the same slope of the given equation $3x-2y=5$ we transform it in a slope intercept form $-2y=5-3x$ $y=\frac{3}{2}x-\frac{5}{2}$ $m=\frac{3}{2}$ For the point slope we use the following $y-y_{1}=m(x-x_{1})$ and plug in the known values $m=\frac{3}{2} $ and $(-1,3)$ Point slope $y-3=\frac{3}{2}(x+1)$ For the slope intercept for we solve for y and simplify $y-3=\frac{3}{2}(x+1)$ $y=\frac{3}{2}x+\frac{3}{2}+3$ $y=\frac{2}{2}x+\frac{9}{2}$
