    for second you answered incorectly a little: look perpendicular line have NEGATIVE reciprocal slopes in your answer the lines have just reciprocal slopes

    ok so for third 1st rewite the equation in slope-intercept form: 2x+6y=-4 in slope intercept it would be y=-1/3x - 2/3

    now we have this equation: y=-1/3x - 2/3 y=-1/3x+b substitute the coordinates: -3=1/3*3+b b=-3-1=-4 so the equation is y=-1/3x-4 now rewite this in standart form and get your answer

    so for the fourth question the slope formula is (y1-y2)/(x1-x2)=(-6+12)/(-3+1)=6/(-2)=???

    we get that the slope of line C is -3. but we need the slope of line perpendicular to line C. So what is the NEGATIVE RECIPROCAL of -3 @kittymeow101 ?

    yes and would this http://prntscr.com/8n6u56 be done the same way?

    yes first count the slope using slope formula i gave you then the slope of the line parallel to the given line would be the same. dont forget that in this question they need slope of parallel line. it would be the same as the slope you will count of line A

    so look: (y1-y2)/(x1-x2)=(2-6)/(1-3)=(-4)/(-2)=4/2=2 the slope of line A is 2 thus the slope of parallel line is.............

    it would be -2 or 2

    slopes of parallel line are equal: as the slope of line A is 2 then it would be 2
