$k:y=m_1x+b_1;\ l:y=m_2x+b_2\\\\k\ ||\ l\iff m_1=m_2\\\\k:y=4x-4;\ l:24x-4y=96\\\\24x-4y=96\ \ \ \ |subtract\ 24x\ from\ both\ sides\\-4y=-24x+96\ \ \ \ |divide\ both\ sides\ by\ (-4)\\y=6x-24\\\\m_1=4;\ m_2=6\Rightarrow m_1\neq m_2$

Answer: The graphs y = 4x - 4 and 24x - 4y = 96 are not parallel.

Answer:

75x + 375 $\geq$ 7500

-375 -375

_________________

75x $\geq$ 7125

divide both sides by 75

x is greater than or equal to 95

What is the slope of the line that had that equation 4x+2y=12

Naddik [55]

Answer:

<h2>- 2</h2>

Step-by-step explanation:

The slope intercept form of an equation of a line:

$y=mx+b$

m - slope

b - y-intercept

We have the equation of a line in the standard form

$Ax+By=C$

Convert to the slope-intercept form:

$4x+2y=12$ <em>subtract 4x from both sides</em>

$2y=-4x+12$ <em>divide both sides by 2</em>

$y=-2x+6$

Therefore the slope is equal to -2.

Other method:

If we have the equation of a line in standard form Ax + By = C

or in general form Ax + By + C = 0, then the formula of a slope is

$m=-\dfrac{A}{B}$

We have A = 4 and B = 2. Substitute:

$m=-\dfrac{4}{2}=-2$
