Which equation represents the line that passes through the points (-4,4) and (8,-2)?

Helen [10]

Answer:

$y=-\frac{1}{2} x +2$

Step-by-step explanation:

$m=\frac{y2-y1}{x2-x1} = \frac{-2-4}{8-(-4)} =\frac{-6}{12} = -\frac{1}{2}$

So for a movement along the x-axis left to right by 2 the y-axis drops by 1

This the equation at this point is =

$y=-\frac{1}{2} x+c$

Pick any of the two points (x,y) . let's choose ( 8 , -2 )

$y2=-\frac{1}{2} x2+c \\\\..\\\\-2=(-\frac{1}{2} )(8)+c\\-2=-4+c\\\\..\\\\c=2$

SO ..

$y=-\frac{1}{2} x+2$

Is x = -3 a solution to 5x + 7 = 4

So, 5 x (-3) + 7 = -15 + 7 = - 8 , but not 4;
Then, -3 is not a solution to 5x + 7 = 4;
