Answer:
F) y=-2x
Explanation:
To find the equation of a line, the formula is:
with m being the slope and y being the y-intercept.
The slope is
where the rise is how many units you go up and down, and the run is how many units you go left and right. To find the slope, first choose 2 points. (-1,2) and (0,0). Next, to get one (-1,2) to (0,0) you have to go down 2 units and right 1, making our slope -2/1 or -2.
The y-intercept is where the line intercepts the y-axis, and this is at (0,0). Since the y-value is 0, we don't have to include the y-intercept in our equation.
We can combine our values to the line equation:
y=-2x
