Hello.
Since we have two points, and we are asked to find the slope of the line, let's use the slope formula:
Where
m is the slope
y2 is the y-coordinate of the second point
y1 is the y-coordinate of the first point
x2 is the x-coordinate of the second point
x1 is the x-coordinate of the first point
In this case, m is unknown, y2 = 4, y1 = 8, x2=2, x1=0
Plug in the values:
Therefore, the slope is -2.
I hope it helps!
Have a nice day!
