What is the image point of (9, 1) after translation left 4 units and up 4 units

(5, 5 )

Step-by-step explanation:

A translation of 4 units left means subtract 4 from the x- coordinate

A translation of 4 units up means add 4 to the y- coordinate.

(9, 1 ) → (9 - 4, 1 + 4 ) → (5, 5 )

Number one is only a function

Step-by-step explanation:

A function has all different x values, but if there are two of the same x values with different y values, that is not a function. It’s okay if there are two do the same x values- they just have to have the same y values.

Number one has all different x values

Number two has an x value with two different y values, therefore it is not a function

Number 3 has two of the same x values but with different y values, so it’s not a function

Number four is not a function because of the vertical line test. You pick a point on the line and draw a vertical line all the way through the line. If that point passes through any other points, that it is not a function. Number four doesn’t pass the vertical line test, so it’s not a function.
