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 ,

$m_{|| \ lines } =\dfrac{4}{5}$

Answer:

y = 4x + 2

Step-by-step explanation:

$\frac{y^{2}-y^{1} }{x^{2} -x^{1} }$

$\frac{6-2}{1-0} = \frac{4}{1}$

y = 4x + 2
