The point slope form or the equation of a line is :
y - y1 = m(x - x1)
First find the slope between the two coordinates:
m = y2-y1/x2-x1
m = 0-4 / 2-(-6)
m = -4 / 8
m = - 1/2
Now create the point slope form / equation of a line:
y - 4 = - 1/2(x - (-6))
y - 4 = - 1/2(x + 6)
OR you can have
y - 0 = - 1/2(x - 2)
Isn't it already in standard form?

Step-by-step explanation:
You multiply the numerator by 1000 and the denominator by 60
Alright. If a slope is negative it is going from right to left, the slope is -1/2 which means the slope is going up -1/2 and to the side -1. Also, the y-intercept is 4, which means the slope runs through the point (0,4). lets put this into the slope equation:
y=mx+b
y = -1/2x + 4
where m = slope
b = y-intercept.
If another line is running parallel, then it will have the same slope but a different y-intercept. Since the other line running parallel runs through the points (1, -5), it means that the y-intercept for this equation is -5.
y = -1/2x + 11/2
Last, a line running perpendicular will simply be the reciprocal of the line it is perpendicular to. Therefore the equation of the line perpendicular to the first line is
y = 2x + 12
