How do I graph x - 4y < 0

Temka [501]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

$x-4y < 0$

isolate the variable y

$-4y < -x$

Divide by -4 both sides

Remember

When you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol

$y > \frac{x}{4}$

The solution of the inequality is the shaded area above the dashed line $y=\frac{x}{4}$

The slope of the dashed line is positive m=1/4

The y-intercept of the dashed line is (0,0)

The x-intercept of the dashed line is (0,0)

using a graphing tool

Write the quadratic equation whose roots are, -4 and 6 and whose leading coefficient is 4

Hitman42 [59]

$\begin{cases} x=-4\implies &x+4=0\\\\ x=6\implies &x-6=0 \end{cases}\qquad \implies (x+4)(x-6)=\stackrel{y}{0} \\\\\\ (x^2-2x-24)=\stackrel{y}{0}\implies 4(x^2-2x-24)=\stackrel{y}{0}\implies {\Large \begin{array}{llll} 4x^2-8x-96=y \end{array}}$
