What is the slope of all lines parallel to the line 4x-5y+-1?
Bond [772]

Given equation of the line ,

\implies 4x - 5y +(-1) = 0

Simplify ,

\implies 4x - 5y - 1 = 0

Transpose terms to RHS ,

\implies 5y = 4x - 1

Divide both sides by 5 ,

\implies \boxed{ y =\dfrac{4}{5}x -\dfrac{1}{5}}

Now we know the slope intercept form of the line as y = mx + c we have ,

  • m =\dfrac{4}{5}

As we know that the slope of all parallel lines are same . Henceforth ,

  • m_{|| \ lines } =\dfrac{4}{5}

Which one of the following is not closed under the operation being performed
Sergeu [11.5K]
Remember that polynomials are closed under addition, subtraction, and multiplication, but they are not closed under division. The only division you have there is B; therefore the correct answer is B.

A. (14x-2)3(x-2)=14 x^{2} -90x+10. The result is still a polynomial; therefore, answer A is incorrect.

B. \frac{(14x-2)}{3(x-2)} =  \frac{14}{3} with a remainder of 26. The result is not a polynomial anymore; therefore, B is the correct answer.

C. (14x-2)+3(x+2)=17x+4. The result is still a polynomial; therefore, answer C is incorrect.

D. (14x-2)+3(x+2)=17x+4. The result is still a polynomial; therefore, answer D is incorrect.
