Answer:
Slope = - 2
Explanation:
Given equation is,
y= - 2x
If x=1, y= -2.
If x=2, y= - 4
Take such few points and plot the graph (1, - 2), (2, - 4)........
Draw a straight line through the points.
For slope, compare the equation with slope intercept form, y=mx + c
Here, c=0 and m=-2
Hope this helps!!
