Aline has a slope of 1/2 and a run = 50. what is the rise? a). 25. b) 50. c) 100

The slope= y/x
the run = x

1/2 = y/50
cross multiply
2y = 50
y = 50/2
y = 25 <=== the rise 

2(10 - 13x) + 9x = -34x + 6020 - 26x + 9x = -34x + distributive property-17x = -34x + subtraction property (subtracted 20 from both sides)17x = addition property (added 34x to both sides)x = 40/ division property (divided both sides by 17)
