@AlexandervonHumboldt2
for the first you answered correctly
for second you answered incorectly a little: look perpendicular line have NEGATIVE reciprocal slopes in your answer the lines have just reciprocal slopes
so would the answer be C?
yes
what do you think for third?
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
@AlexandervonHumboldt2 Hallo mein Name ist SweetBeat , wie ist Ihr Name und was ist dieses " Steigungsschnittform" Du willst diese Person sagen? Sie sprechen Deutsch , ja? Oder Nein?
ok give me a second
Wenn Sie mir bei etwas helfen , das wirklich machen würde mein Tag !|dw:1443861916216:dw|
wait i seems to make a mistake
i got 3y+x=12
-12*
Entschuldigen Sie , aber könnten Sie mir helfen? @ AlexandervonHumboldt2
yeah i sems to make a mistake let me redo
it should have been 3y+x=-6
yeah i redid it it is 3y+x=-6 @kittymeow101
ok lets move to fourth question
so thats the final answer
yeah
ok
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 ?
-1/3?
no
1/3 instead of -1/3
does that make sense?
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
ok ty sooooooo much for helping
