The slope of a line going through points (5,7) and (3,1) is 6/2 so 3/1 = slope of 3
Answer:
thank me
Step-by-step explanation:
Use the foil method to multiply out the expressions. Then solve for x by first combining like terms and then using inverse properties
check the picture below.
notice, a function that is decreasing, namely have a negative slope, doesn't have to be negative.
