find an equation of the line through the given points. give the final answer in slope-intercept form (-2,2) (4,-1)

Pachacha [2.7K]

to get the equation of any straight line, we simply need two points off of it, let's use the points in the picture below.

$(\stackrel{x_1}{-2}~,~\stackrel{y_1}{2})\qquad (\stackrel{x_2}{4}~,~\stackrel{y_2}{-1}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-1}-\stackrel{y1}{2}}}{\underset{run} {\underset{x_2}{4}-\underset{x_1}{(-2)}}}\implies \cfrac{-3}{4+2}\implies \cfrac{-3}{6}\implies -\cfrac{1}{2}$

$\begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{2}=\stackrel{m}{-\cfrac{1}{2}}(x-\stackrel{x_1}{(-2)}) \\\\\\ y-2 = -\cfrac{1}{2}(x+2)\implies y-2=-\cfrac{1}{2}x-1\implies y=-\cfrac{1}{2}x+1$

What is the correct choice

Mekhanik [1.2K]

I think it would be A.

Maybe not because they are all negatives.

Help, how do I solve this

notsponge [240]

Given 14 = adjacent
16 = hypothenuse
SOHCAHTOA
You can use CAH (cosine)
Cos^-1 = 14/16 = 28.9
The solution is 29 degrees

Apply the distributive property to create an equivalent expression. \dfrac12(10x + 20y +10z) = 2 1 (10x+20y+10z)=start fractio

Fiesta28 [93]

Answer:

The answer is " $5x+10y+5z$ "

Step-by-step explanation:

Given value:

$\to \frac{1}{2}(10x + 20y +10z)$

Using the distributive property.

If there are three integers a,b and c then:

$a \cdot(b+c) =a \cdot b + a \cdot c$

$\to \frac{1}{2}(10x) +\frac{1}{2}(20y+10z)\\\\\to (5x) +\frac{1}{2}(20y+10z)$

Again apply the distributive property

$\to (5x) +(10y+5z)\\\\\to (5x+10y+5z)$

Or

$\to \frac{1}{2}(10x + 20y +10z)$

take common 2 from the equation:

$\to \frac{1}{2}\times 2 (5x + 10y +5z)\\\\\to (5x + 10y +5z)\\$
