Step-by-step explanation:
Answer:
5x + 4y - 4 = 0 is the given line equation.
Step-by-step explanation:
The slope m of the line is given as 
The point of the equation is (x0, y0) = (-4, 6)
Now, by POINT SLOPE formula of a line:
Equation of a line is : ( y -y0) = m (x - x0)
Hence, the equation is 
On further simplifying
,
⇒ 5x + 4y - 24 + 20 = 0
or, 5x + 4y - 4 = 0 is the given line equation.
Answer:
C
Step-by-step explanation:
"binomial" the operation between two terms (B or C)
"3rd degree binomial" the highest degree of the polynomial's monomials (individual terms) with non-zero coefficients have to be "3"
Answer:
b
Step-by-step explanation:
Displacement and distance have different meanings. Displacement is a vector quantity and is the objects overall change in position. Distance is scalar quantity which describes how much ground an object covers during motion.
If they have covered 4 miles from a origin and we don't know the origin but we know that they start there and continue for 4 miles. It will be displacement if they started at a distance and walked a certain distance and the difference from start to finish is 4 miles. Therefore, it must be distance because we don't know the initial position and only that they walked 4 miles.
Mark is right if their starting point is a origin of a coordinate system
1/4 = y/12
12/4 = y
y = 3
Answer: y = 3
Check work
1/4 = y/12
1/4 = 3/12
Correct!
