The domain of a relation R is the set of real numbers. x is related to y under relation R if dxe ≤ dye . Select the description that accurately describes relation R and justify your selection. (a) Symmetric (b) Anti-symmetric (c) Anti-reflexive (d) Neither symmetric nor anti-symmetric
step-by-step explanation:
i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.
i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).
in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.
then the standard form of the equation is finding an expression of y in function of x
y-1=1/4*(x-12)
y=x/4-3+1
y=x/4-2
hope that .
do you confirm there was a mistake in the question?
