Which equation represents the line that passes through the points (-5,2) and (9,0)

V125BC [204]

Step-by-step explanation:

Given points 

( -5 , 2) and (9 , 0)

First calculating slope(m)

= ( y2 - y1) / ( x2 - x1) 

= ( 0-2) / ( 9+5)

= -2 / 14

= -1/7

Now The equation of line is given by 

y - y1 = m ( x - x1) 

y -2 = -1/7 (x + 5)

7( y - 2) = -1(x + 5)

7y - 14 = -x -5

x + 7y -14 +5 = 0

x + 7y - 9 = 0 

Which is the required equation

Lots of point up for grabs

Burka [1]

Minus a from both sides
x-a=-2by²
times both sides by -1
a-x=2by²
divide both sides by 2b
$\frac{a-x}{2b}=y^2$
sqrt both sides
$y= \sqrt{\frac{a-x}{2b}}$
