Question

The graph of 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: 2


    The line equation y = mx + b; m = Slope of the line & b is the y -intercept.
    The slope of line is fraction numerator text  change in  end text y over denominator text  change in  end text x end fraction
    (-2,0) & (0,4) are two points on line

    m equals fraction numerator 4 minus 0 over denominator 0 minus left parenthesis negative 2 right parenthesis end fraction equals 4 over 2 equals 2.

    Interior angles are the angles contained within a shape or the region enclosed by two parallel lines transversely intersected.
    ¶Interior angles form in two ways in geometry. The first occurs within a polygon, and the second occurs when a transversal cuts parallel lines. Angles are classified into various types based on their measurements. Other angles are known as pair angles because they appear in pairs to exhibit a specific property. Interior angles are one example.
    ¶Sum, S = (n − 2) × 180°

    Use polynomial identities to factor the polynomials or simplify the expressions : 8 cubed minus 2 cubed

    Polynomial identities are equations that are true for all possible values of the variable. We can perform polynomial multiplication by applying the distributive property to the multiplication of polynomials.
