Question


The graph of the equation y=mx + b, where m and b are constants, is shown in the xy-plane. What is the value of m?

The correct answer is: 1.5


    The points on the line are (0, 2) & (-2, -1)
    The slope m equals fraction numerator y subscript 2 minus y subscript 1 over denominator x subscript 2 minus x subscript 1 end fraction equals fraction numerator negative 1 minus 2 over denominator negative 2 minus 0 end fraction equals fraction numerator negative 3 over denominator negative 2 end fraction equals 3 over 2 equals 1.5.
