Question

Can you help me with this

Answer 1

Y = -1/2 x

Explanation:

To write the equation in slope intercept form

Y = mx + c

C is y-intercept

the graph is passing through centre. That means y-intercept is zero.

so C=0

To find m which is slope,

`(rise)/(run)`

rise = 10

run= -20

`(10)/( - 20) \\ ( - 1)/(2)`

So

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