Is (4,7) a solution for y=2x-1 Show the work you did to check the solution Please help!!

Yes, it is a solution

Step-by-step explanation:

To determine if a point is a solution for a line, you have to substitute the x and y coordinates from the point into the x and y variables in the equation of the line. Then, you need to determine if the equation makes sense, as in the two sides end up equal to each other.

x = 4

y = 7

y = 2x - 1

7 = 2(4) - 1

7 = 8 - 1

7 = 7

Since the equation makes sense, as in 7 is equal to 7, we are able to determine that the point (4,7) is a solution for y=2x-1 because it falls on the line.
