Given equations : Equation A: 4y -3x =16 and
Equation B: -x-8y =3.
We are given a<em> point (-5,0.25) plugging it in first equation</em>
4(0.25) -3(-5) =16
1+15 =16.
16 =16 <em>: Satisfies first equation.</em>
Plugging (-5,0.25) it in second equation.
-(-5)-8(0.25) =3.
5 - 2 = 3.
3=3 <em>: Satisfies first equation.</em>
<h3>Therefore, they are the only values that make both equations true.</h3>
y-axis
That last sentence though, I died reading that.
The formula for direct variation is y = k × x and the formula for inverse variation is y = k/x
The direct variation represented by the equation
y ∝ x
Its is y directly proportional to x
Where x is the independent variable
y is the dependent variable
By replacing the ∝ sign with the equal sign. The equation will be
y = kx
Where k is the constant of proportionality
Similarly the inverse variation is
y ∝ 1/x
Replace the ∝ sign with the equal sign
y = k/x
Therefore, the direction variation represented by y = k × x and inverse variation represented by y = k/x
