Answer
$y=2x+1$
$y=-2x+9$
Work Step by Step
The first line passes through $(2.5)$ and $(1,3)$
Its slope is 2 and y-intercept is 1.
So the equation is $y=2x+1$
the second line passes through $(2,5)$ and $(3,3)$.
The slope is -2 and we can use point-slope form to find the equation:
$y-y_1=m(x-x_1)$
$y-3=-2(x-3)$
$y-3=-2x+6$
$y=-2x+9$
