Find the ordered pair solution of y = (2/5)x + 2 corresponding to -5

1 Answer

  • The ordered pair solution of y = (2/5)x + 2 corresponding to -5 is (x, y) = (-5, 0)

    Solution:

    Given that we have to find the ordered pair solution of [tex]y = \frac{2}{5}x + 2[/tex] corresponding to -5

    Let us find the ordered pair corresponding x = -5

    Ordered pairs are often used to represent two variables

    The number which corresponds to the value of x is called the x-coordinate and the number which corresponds to the value of y is called the y-coordinate

    Substitute x = - 5 into the function and evaluate for y

    [tex]y = \frac{2}{5}x + 2\\\\y = \frac{2}{5}(-5) + 2\\\\y = 2(-1) + 2\\\\y = -2 + 2\\\\y = 0[/tex]

    Therefore the ordered pair is x = -5 and y = 0 which is (x, y) = (-5, 0)
