What is the slope of the line containing (-2, 5) and (4,-4)?

Pachacha [2.7K]

Answer:

Option C is correct.

Step-by-step explanation:

<h2> $slope \: = \: \frac{y2 - y1}{x2 - x1}$ </h2><h3> $= \frac{ - 4 - (5)}{4 - (2)}$ </h3><h3> $= \frac{ - 9}{4 + 2}$ </h3><h3> $= \frac{ - 9}{6}$ </h3><h3> $= \frac{3( - 3)}{3 - 2}$ </h3><h3> $= - \frac{3}{2}$ </h3><h3>Hope it is helpful....</h3>

Which equation shows the quadratic formula used correctly to solve 5x2 + 3x – 4 = 0 for x? x = StartFraction negative 3 plus-or-

Brrunno [24]

Answer: FIRST OPTION

Step-by-step explanation:

<h3> The missing picture is attached.</h3>

By definition, given a Quadratic equation in the form:

$ax^2+bx+c=0$

Where "a", "b" and "c" are numerical coefficients and "x" is the unknown variable, you caN use the Quadratic Formula to solve it.

The Quadratic Formula is the following:

$x=\frac{-b \±\sqrt{b^2-4ac} }{2a}$

In this case, the exercise gives you this Quadratic equation:

$5x^2 + 3x - 4 = 0$

You can identify that the numerical coefficients are:

$a=5\\\\b=3\\\\c= - 4$

Therefore, you can substitute values into the Quadratic formula shown above:

$x=\frac{-b \±\sqrt{b^2-4ac} }{2a}\\\\x=\frac{-3 \±\sqrt{(3)^2-4(5)(-4)} }{2(5)}$

You can identify that the equation that shows the Quadratic formula used correctly to solve the Quadratic equation given in the exercise for "x", is the one shown in the First option.

Find the slope of the following ^ :))<br> |

Luba_88 [7]

Answer:

m [slope] = 0

Step-by-step explanation:

When the slope is 0, x cancels out so the y value will remain the same.

There are several methods to finding slope but the easiest way to do this is by dividing the second y value - first y value by the second x value - first x value.

m = ∆y/∆x = y2-y1/x2-x1

You y2 and x2 are interchangable with y and x, because y1, and x1 are part of the starting coordinate,.

The reason you subtract the second

value from the first is because in a directly proportional relationship, y increases as x increases so the next x values will have a greater y value, this is a measure of steepness.

So the slope is:

-1 - -1 / 3 - -2 = -1 + 1 / 3 + 2 = 0 / 5 = 0.
