F.
y = - x

Answer 1

F

Explanation:

Answer 2

The answer is option F

Explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To calculate the equation of the line first find the slope

Slope of the line using points

(0 , 0) and (4 , -2) is

`m = ( - 2 - 0)/(4 - 0) = ( - 2)/(4) = - (1)/(2)`

Now use the formula

y - y1 = m(x - x1) to find the equation of the line using any of the points

Using point (0,0)

That's

`y - 0 = - ( 1)/(2) (x - 0)`

The final answer is

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

Hope this helps you
