Tcecarenko [31]

Answer:

angle is 45° which is constant

Step-by-step explanation:

We use formula for two vectors a and b to calculate angle θ between them by formula

cos θ = a . b / magnitude of a  × magnitude of b

Y=(3/5)x -3 and 5y =3x-10 these lines are and the second question?

azamat

Look at the first line: y = (3/5)x - 3. What happens if you multiply each term by 5, to eliminate the fraction?

5y = 3x - 3

Compare this to the second equation,

5y - 3x = -10, or 5y = 3x - 10.

The coefficients of x and y (as 3 and 5 here) determine the slope of a straight line. Since 5y = 3x is present in both equations, the two lines MUST be parallel.

y = 4
4y = 6 => y = 6/4

y+4 and y =3/2 are both horizontal lines. Since they are horiz., they are parallel.
