Question

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

Answer 1

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
`y = (2)/(5)x + 2` 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

`y = (2)/(5)x + 2\\\\y = (2)/(5)(-5) + 2\\\\y = 2(-1) + 2\\\\y = -2 + 2\\\\y = 0`

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