Question 426715


1) 6x+6y=30 

=> 6y = -6x +30

=> y = -x + 5    (divide both sides by 6)

=> y = -x + 5

now, it is in slope- intercept form, slope = -1, y -intercept = 5


2) -3/2x+5/4y=15/4 

=> -6x + 5y = 15 (multiply both sides by 4 to remove fraction)

=> 5y = 6x + 15 

=> y = (6/5) x + 3

now, it is in slope - intercept form, slope = 6/5, y -intercept = 3
