A line passes through the points (2,-2) and (-6,2). The point (a.-4) is also on the line. What is the value of a?

Zigmanuir [339]

Answer:

6

Step-by-step explanation:

Hey there) The formula of your line is:

$-2=2k+b\\2=-6k+b\\=>4=-8k\\k=-0.5\\=> b=-2+1=-1\\=>y=-\dfrac{1}{2}x-1\\$

If point has y=-4, then:

$-4=-\dfrac{1}{2}a-1\\4=\dfrac{1}{2}a+1\\a=6$

Hope this helps) Have a nice day/night :)
