Line ab has an equation of a line y = 5x − 2. which of the following could be an equation for a line that is parallel to line ab? y = 5x + 3, y = 1 over 5x + 3, y = −5x + 3, y = −1 over 5x + 3

y = 5x + 3

Step-by-step explanation:

Parallel lines have the same slope.

Your function is

y= 5x - 2

slope = 5

The line must have slope = 5.

(a) y = 5x + 3

slope = 5, ∴ Parallel.

(b) y = 1/(5x) + 3.

Not a straight line. ∴ Not parallel.

(c) y = -5x +3

slope = -5 ∴ Not parallel.

(d) y = -1/(5x )+ 3

Not a straight line. ∴ Not parallel.

The Figure below shows the graph of y = 5x -2 (black) and that of the parallel line y = 5x + 3 (green).

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
