    First, I believe you have to decide what points you want to use to get the slope of -1/2

    so how do i write an equation of a line that has a slope of -1/2 in point-slope form, and slope-intercept form.

    yup, so then we have y+1=-1/2 x -4

    now i have 10 problems of standard form to do and 15 problems to do of parallel and perpendicular lines but i don't want to keep bothering you.

    oh, don't worry, it will help me! I am in "Enriched Algebra" and I just learned that, and I understand it really well - helping you will help me study and practice!
