Question

explain the steps you would take to determine if the point (4,7) is a solution to the equation y=1.25x+2

Answer 1

Point (4,7) completely satisfies the equation and is a solution to the equation.

Explanation:

Given:

Equation:
`y=1.25x+2`

To check if the point (4,7) is a solution to the given equation.

Solution:

The solution of an equation is given as
`(x,y)` which completely satisfies the equation.

To check if the point (4,7) is a solution to the given equation, we will plugin
`x=4` and
`y=7` in the given equation and see if it satisfies it or not.

Plugging in point (4,7) in the equation:

`7=1.25(4)+2`

Simplifying.

`7=5+2`

`7=7`

The above equation is always true, and hence point (4,7) completely satisfies the equation and is a solution to the equation.
