Give an ordered pair (a,b) of numbers that satisfy the equation.

I got (1,1)
but cant i also be (2,4)?
I'm not sure how to answer that

Also,

Write each equation for the vertical and horizontal lines passing through the point (7,-5) in (x,y) - coordinates

I do not know to do this.

You did not provide the equation, so there is no way of telling if your pair of numbers satisfies the equaiton.

Ah sorry.

Equation:

3a-b=2

For the first question:

The equation you mentioned is not explicitly provided, so it's difficult to determine the validity of the ordered pair (2,4). However, if you substitute the values of a and b into the equation and find that it satisfies the equation, then (2,4) can indeed be a valid solution. It's important to note that some equations may have multiple ordered pairs that satisfy them.

To answer math questions like this, you need to be given the equation you are working with. If you are not provided with a specific equation, you can clarify by asking for it or providing more information.

For the second question:

To write equations for vertical and horizontal lines passing through a given point (7, -5) in (x, y) coordinates, you need to understand the characteristics of these types of lines.

1. Vertical line: A vertical line has a constant x-coordinate and can be written as an equation of the form x = a, where "a" is the constant x-coordinate. Since the line passes through the point (7, -5), the equation for the vertical line would be x = 7.

2. Horizontal line: A horizontal line has a constant y-coordinate and can be written as an equation of the form y = b, where "b" is the constant y-coordinate. Since the line passes through the point (7, -5), the equation for the horizontal line would be y = -5.

Remember, the key is to identify which coordinate (x or y) remains constant for each type of line. For a vertical line, the x-coordinate remains constant, and for a horizontal line, the y-coordinate remains constant.
