If a = -12/5, then 5x + 2y = 6 and 3x - ay = 4 are parallel. FALSE.
5x + 2y = 6;
2y = -5x + 6
y = -5/2x +3 the slope of which is -5/2
3x - ay = 4 when a = -12/5,
3x + 12/5y = 4
12/5y = -3x + 4
y = -5/4x + 5/3 the slope of which is -5/4
the slope of the above two lines are not the same so they are not parallel.

Input in standard form the equation of the given line. The line with m = -3/2 and b = 6
Updated 4/23/2014 7:17:33 PM
The equation for the line with m = -3/2 and b = 6 is y = -3/2x + 6, rewritten in standard form it is 3x + 2y = 12

Weegy: 7/3 is the y-intercept of the line whose equation is 3x + 2y = 7. User: Ben has \$3.40 consisting of quarters and dimes. How many coins of each kind does he have if he has 22 coins? Which of the following system of equations represents the word problem if d is the number of dimes and q is quarters? d + q = 22 and 10d + 25q = 340 10d + 25q = 22 and d + q = 340 dq = 22 and d + q = 340 Weegy: d + q = 22 and 10d + 25q = 340- is the system of equations that represents the word problem if d is the number of dimes and q is quarters.

The y-intercept of the line whose equation is 3x + 2y = 7 is 7/2.
Y intercept is the value when x = 0
3(0) + 2y = 7
2y = 7
y = 7/2
