A = 8i + 6j
b = 4i + 5j
ab = (8i + 6j)(4i + 5j)
ab = 8i(4i + 5j) + 6j(4i + 5j)
ab = 8i(4i) + 8i(5j) + 6j(4i) + 6j(5j)
ab = 32i² + 40ij + 24ij + 30j²
ab = 32i² + 64ij + 30j²
ab = <32, 30>
The answer is D.
I think it may be 1,680B but I'm not too sure...
Answer:
y=-3/4x - 7
Step-by-step explanation:
When finding the slope given a point and a slope, we do the following.
y=mx+b (Slope-intercept Form)
m is the slope and x,y are the points
Plug in everything
-1= -3/4(-8)+b
Multiply
-1 = 6 + b
-7 = b
This gives us the final equation of y=-3/4x - 7
