Write the equation of the line that is perpendicular to the line 2x − 3y = 3 and passes through the point (−8, 2). y = 2/3x − 10 y = 2/3x + 10 y = −3/2x − 10 y = −3/2x + 10
If its perpendicular, then the slope is is the negative reciprocal of the original slope
so if the slope was 5x then the perpendicualr slope is -1/5x
so the answer is A?
nope first you gotta get it into y=mx+b form
can you solve for y?
yes Y=mx+b
i mean B is the answer
i meant in the above equation its not in the form Ax+By=C
B is totes the answer right?
not quite you gotta do a little work first here: 2x − 3y = 3
how about C
-3y=-2x+3 y=2/3x-1
now m=slope has to be the opposite reciprocal, do that
and then pllug the slop in, with the point, in the point slope formula which is y-y1=m(x-x1) where y1=2 and x1=-8 and when you solve for y, you get your answer
ca you solve for y for me idk how 2 do it
I'm here to help not answer but what is the negative reciprocal of 2/3?
whats reciprocal
the reciprocal of \[\frac{ a }{ b } is =\frac{b}{a}\]
so the answer is -3/2
yes now with m=-3/2 y1 being the y coordinat of (-8,2) and x1 being the x coordiante of it, plug the slope and the point into the point slope formula and tell me what you get (the other x and y dont change) \[y-y1=m(x-x1)\]
the answer is C
you got it
woo!
