Is (2,5) a solution of y=1/2x+4?

To solve this problem, you need to plug the given integers in for the variables in the equation and solve.

So, (2,5) means that x=2 and y=5.

When we put this into the equation, we get (5) = 1/2(2) +4

To simplify this equation, first we should multiply 1/2 by 2.

1/2*2=1, so your equation is now 5=1+4

1+4 =5, so the equation would be 5=5.  This is a true statement, so you know that your ordered pair, (2,5) is a solution of the equation.

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.
