The answer is y = -1/5x + 5
Perpendicular means the opposite reciprocal of the slope. The reciprocal of 5 would be 1/5. The opposite sign would be negative, so -1/5.
The equation that you use is y - y1 = m(x - x1)
The point is (-15,8).
x1 = -15
y1= 8
m= -1/5
y - 8 = -1/5(x - (-15)).
The 15 becomes positive.
y - 8 = -1/5(x+15)
Distribute
y - 8 = -1/5x - 3
Add 8 to both sides
y = -1/5x + 5
we need to know how many their are in the drama clud first
A1 = (1, -2 , 0) ; a2 = (0,1,2) ; a3 = (5,-6,8) ; b = (2,-1,6)
2*a1 = (2, -4,0)
3*a2 = (0, 3, 6)
-------------------
sum = (2, -1, 6) = b

Answer:
y = 2x - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2, thus
y = 2x + c ← is the partial equation of the line
To find c substitute (2, 1) into the partial equation
1 = 4 + c ⇒ c = 1 - 4 = - 3
y = 2x - 3 ← equation of line
