Answer:
[tex]y=-\frac{1}{2} x+1[/tex]
Step-by-step explanation:
→ Pick 2 coordinates
( 0 , 1 ) and ( 2 , 2 )
→ Find the gradient
[tex]\frac{2-1}{0-2}= -\frac{1}{2}[/tex]
→ Write into y = mx + c
y = -0.5x + c
→ Substitute in ( 0 , 1 )
1 = 0 + c
→ Find c
c = 1
→ Rewrite everything into y = mx + c
[tex]y=-\frac{1}{2} x+1[/tex]
