The "dot product" of two vectors has several different formulas.
Since you are given the x- and y-coordinates of both vectors a and b, we can apply the formula
a dot b = ax*bx + ay*by, where ax=x-component of vector a, by=y comp of vector b, and so on.
So, for the problem at hand, ax * bx + ay * by becomes
3(-2) + (-8)(-6) = -6 + 48 = 42 (answer). Note that the dot product (or "scalar product" is itself a scalar.

Answer:
x=8
Step-by-step explanation:
2*3x=6x
2*-7=-14
6x-14=34
6x+14=34+14
6x=48
6x/48
x=8
Answer:
y=4x-5
Step-by-step explanation:
y-y1=m(x-x1)
y-3=4(x-2)
y=4x-8+3
y=4x-5
