Question

Is the point (7,10) a solution of the equation y = 18x-10?
O Yes
O No

Answer 1

Our answer is: No.

`\Large\textsl{Explanation}`

We are asked to identify if (7,10) is a point on the line:
`\boldsymbol{y=18x-10}`.

So, we substitute 7 for x, since it's our x-coordinate, and 10 for y, since it's the y-coordinate.

`\implies\sf{10=18(7)-10}`

`\implies\sf{10=126-10}`

`\implies\sf{10=116}`

Obviously, 10 is not equal to 116, so, we have a false statement, which means that (7,10) is not a solution to y = 18x - 10.

`\therefore` It's not a solution.

Answer 2

No

Explanation:

to determine if (7, 10 ) is a solution.

substitute the x- coordinate , 7 into the right side of the equation and if the value obtained is equal to the y- coordinate , 10, then it is a solution.

y = 18x - 10 ( substitute x = 7 )

y = 18(7) - 10 = 126 - 10 = 116 ≠ 10

Then (7, 10 ) is not a solution to the equation.
