What is the equation of a line that passes through the point (6,3) and is perpendicular to a line with a slope of -3/2
SCORPION-xisa [38]

Answer:

  none of the above

Step-by-step explanation:

The perpendicular line will have a slope that is the negative reciprocal of the given slope, so it is ...

  m = -1/(-3/2) = 2/3

The point-slope form of the equation of the line with slope m through point (h, k) can be written ...

  y = m(x -h) +k

For this slope and the point (6, 3), the equation of the line is ...

  y = (2/3)(x -6) +3

  y = 2/3x -4 +3

  y = 2/3x -1 . . . . . matches none of the offered choices

_____

The attached graph shows this equation is the one that goes through the given point.

Is this correct?!! Please be honest and correct me anything
vladimir2022 [97]
Number 2 is wrong because it says NO more than so it would be the opposite of a more than sign. So it should be a less than or equal to sign.
The same goes for number 4. 
Number 5 is wrong as well because since it is the maximum then it cannot be higher than 8, so there so be a less than or equal to sign.

OR 17/100, the denominator means what place it is in. The denominator is100, so it's in the hundredth place. 0.17
