Using the point slope form y - y1 = m(x-x1)
m is the slope, because the lines are parallel the slope is identical, so m = -2.
Replace x1 and y1 with the given point and then solve for y:
y - 1 = -2(x-4)
Simplify:
y - 1 = -2x + 8
Add 1 to both sides:
y = -2x +9
One type that is easy to control are physical variables, sometimes called situational variables that have to do with the physical space or situation of the experiment.

There is no graph, but it should be the one thats a parabola but its kind of wider
