Question

Please help, it is a graph question

Answer 1

guessing

y= 1/2x + 1/2

did y2 - y1/ x2-x1

which gave

-3

-6

also it passed through the y axis at +1/2

Answer 2

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

Explanation:

choose 2 points to find slope

(1,1) (-3,-1)

`m = ( - 1 - 1)/( - 3 - 1) = (1)/(2)`

y-y1 = m(x-x1)

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

y = 1/2x + 1/2
