( 1 ) First graph -

x-intercept = 2

y-intercept = -4

y=2x-4

[ Proof ]

$2x-4=0\\2x=4\\x=2$

For y-intercept, it's y = 0 -4 = -4

( 2 ) Second graph -

x-intercept = 2

y-intercept = 1

slope = -1/2

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

[ Proof ]

$-(1)/(2)x+1=0\\-x+2=0\\-x=-2\\x=2$

For y-intercept, it's y = 0 + 1 = 1

So it's y = 2x - 4

and y = -1/2x + 1
