  • 2. 

    The form of a function that is written as ax+by=c is __________ form.

    Explanation
    The form of a function that is written as ax+by=c is called the standard form. In this form, the coefficients of x and y are represented by a and b respectively, and c is the constant term. Standard form is often used in mathematics to represent linear equations in two variables.

    What is '2x+3y=18' in slope intercept form?

    • Y=-2x+18

    • Y=-(2/3)x+18

    • Y=-(2/3)x+6

    • Y=2x+6

    • Y=(2/3)x+18

    Correct Answer
    A. Y=-(2/3)x+6
    Explanation
    The equation '2x+3y=18' can be rearranged into slope-intercept form, which is y=mx+b, where m represents the slope and b represents the y-intercept. By isolating the y-term, we can rewrite the equation as y=-(2/3)x+6. This means that the slope of the line is -2/3 and the y-intercept is 6.

    What formula describes the line presented to you on the board? (in slope intercept form)

    • Y=2x+6

    • Y=x+3

    • 2x+3y=17

    Correct Answer
    A. Y=x+3
    Explanation
    The correct answer is y=x+3. This is because the equation is already in slope-intercept form, which is y=mx+b, where m represents the slope and b represents the y-intercept. In this case, the slope is 1 (since the coefficient of x is 1) and the y-intercept is 3. Therefore, the equation y=x+3 describes the line presented on the board.
