Step-by-step explanation:
Combine like terms: 40 + 60 = 100 2x = 100 Divide each side by '2'. x = 50 Simplifying x = 50.
Slope equals rise over run. Rise is referring to y values and run is referring to X values. so if they say tests are the Y axis then you use 27 as the rise and 36 as the run. once you have the fraction it is simply reducing the fraction.
27/36= 9/12 = 3/4
