    Lets Do this step by step Do you know parallel and perpendicular lines ? And how the slope change in relation to each

    When a line is parallel to a line then the slope stays the same |dw:1343935655688:dw| Here as you can see the lines will never meet because the slopes are the same althought the y intercepts can be different, even if the slopes were 2 for the first line and 1.9 for the second they wound not be parallel *When a line is parallel to another line the slope is the same Perpendicular lines intersect at 90 degrees and for that to happend the slope must be the opposite reciprocal so if a line is parallel to 1/2, we find the reciprocal which is 2/1 and change it from a positive to negative so it becomes -2/1 Do you get this much

    3x + y = 7 Here you need to find the equation of the line which is perpendicular to this equation so right of the bat we need to make this in to y=mx+b format right so we can get the slope Do you know how to change it in to y=mx+b format?

    Convert 3x + y = 7 in to y=mx+b @drakelovermel

    This is algebra 3x + y = 7 you need to isolate y amd move everythin g on the right side y=-3x+7
