Parallel to 2x+3y=5, will have the same slope, which if solve for y in terms of x and look at coefficient on x, is . Such line to pass through the given point, using point-slope form, is .

Perpendicular to 2x-3y=5, will have a slope negative reciprocal of that for this given line. Solve this given equation for y in terms of x, take the negative reciprocal of coefficient on x, and it will be . The line passing through the given point with this slope is, in point-slope form, .

converting between point-slope and slope-intercept forms

That should help you see how to also understand the standard form Ax+By=C. You CAN find the slope if you learn how to read this form of equation.

The work I described and did, could be done all in standard form, if you learn to read and use the standard form equation.
