Write the equation of the line, in 1. point-slope form and 2. slope-intercept form, that contains the points (-2, 2) and (2, -2).

Pont slope is
y-y1=m(x-x1)
the slope is m and a pont is (x1,y1)

first find slope
slope between (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)
given
(-2,2) and (2,-2)
slope=(-2-2)/(2-(-2))=(-4)/(2+2)=-4/4=-1

a point is either (-2,2) or (2,-2)

1. point slope

y-2=-1(x+2) or
y+2=-1(x-2)

2.
slope intercept
solve for y in any equation
y-2=-1(x+2)
expand
y-2=-x-2
add 2
y=-1x

It is true that organism need food. but cells do not need food. the energy required by the cell for various chemical activities is released by mitochondria in the form of atp (adenosine triphosphate). atp is know as energy currency of the cell.hope it
