Question

For what value of 's' the lines 2x + 3y = 7 and sx + 6y = 8 are parallel?

Answer 1

Answer:

s = 4

Step-by-step explanation:

If two lines are parallel, their slopes are equal.

Slope of a line with the general equation is given by

$\frac{-Coefficient of x}{Coefficient of y}$

Slope of 2x+3y=7 is -2/3 and slope of sx+6y=8 is -s/6

-2/3=-s/8

s = 4
