Find an equation for the line below

lilavasa [31]

Answer:

$y+1=\frac{-2}{3} (x+4)$

Step-by-step explanation:

you can use the equation point-slope of a line

(y-y1)= m(x-x1)

m is the slope =rise /run

to get from the lower point on the line to the other you rise 4 units and run -6 units so m= -4/6= -2/3

now that you have the slope pick you need one point

pick any poin on the line for example (-4, -1)

now you substitute into the point-slope equation point (-4,-1) and slope -2/3

(y+1)= -2/3(x+4)

in standard form will be

y= $\frac{-2x}{3} -\frac{2*4}{3} -1$

y= $\frac{-2x}{3}- \frac{5}{3}$

Remer<br> 1) 5k? + 10k + 6 = 0

IceJOKER [234]

Ignoring the "?" in your question:

$5k+10k+6=0 \iff 15k+6=0 \iff k=-\dfrac{6}{15}$

If the "?" is a squared symbol that wasn't caught:

$5k^2+10k+6=0$

Use the quadratic formula

$x_{1,2}=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}$

to get the solutions:

$x_{1,2}=\dfrac{-10\pm\sqrt{100-120}}{10}$

as you can see, the discriminant is negative, so the equation has no solution.
