Substitute & Equations

Today in math class we continued learning about slopes and graphs. Today Mr. S gave us a worksheet. We had to graph the equation given to us on the worksheet and tell if it is steep, if "y" decreases or increases, give the y-intercept, and tell if the slope goes up fromm left to right. The worksheet was basically very easy to understand after Mr. S went over some of the columns like telling if the "y" increases or decreases. We finished the worksheet in class and if we didn't finish it in class then we would have to finish it for homework. We also learned that if we substituted the coordinates in the equation: y = 3x + 1; (2,7) then we would know if the coordinates were right or not. For example, if we substited 2 for "x" in the equation and 7 for "y" then the equation would be true because 7 = 3(2) + 1 is a true statement. If the coordinates you substituted in aren't true then you would know that the coordinates are wrong.
