Question

Can you help me with this

Answer 1

Answer:

Y = -1/2 x

Step-by-step 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,

$\frac{rise}{run}$

rise = 10

run= -20

$\frac{10}{ - 20} \\ \frac{ - 1}{2}$

So

$y = \frac{ - 1}{2} x$
