Answer:
y = 1/2x - 6
Step-by-step explanation:
slope = 1/2 = m
lets find your y-intercept using slope intercept form: y = mx + b using the points they gave us (6, -3)
y = mx + b; plug what we know to find b, which is our y-intercept.
-3 = 1/2(6) + b
-3 = 3 + b
-6 = b
Now you have all you need to write your equation
y = mx + b
y = 1/2x - 6
Do pemdas the answer all together is = 3
Answer:1084
Step-by-step explanation:you take 126 x 9 and if the teachers are free you leave them out and you get ten dollars for every 25 students and 5 x 25 is 125 that means you take your answer from 126 x 9 and subtract 50 and it leaves you with 1084

Answer: -76 (choice C)</h3>
Explanation:
We're applying the dot product.
u dot v = 3*(-4) + (-8)*8
u dot v = -12 - 64
u dot v = -76
The idea is that we multiply the x coordinates together, and the y coordinates together separately. Afterward you add the products. The result of any dot product is a scalar value, aka a single number.
The dot product is useful in many applications. One of which is to determine if two vectors are orthogonal.
