Mathematics Determine whether the lines will be perpendicular when graphed.

For two lines to be perpendicular, the slope of one line must be the negative reciprocal of the slope of the other line. The slope can be determined by transforming the equation to its standard form of y = mx + b, where m = slope. Thus,

2y = 6 2y = 3x - 6 3/2x - 3, where m = 3/2

For the other line to be perpendicular, the slope of the equation for 2x + 3y = 6 MUST be m = -2/3. To check this, the equation can be transformed to its standard form:

3y...

The number of seats in the non-smoking section is 73 more than twice the number of seats in the smoking section. How many seats are in each section?
Let x = non-smoking seats, and y = smoking seats, with the total of x + y = 205.

From the conditions listed above, x = 2y + 73. Substituting for x in the original equation, we get 205 = 2y + 73…
