Question

The graphs of linear functions f and g are shown. Enter the solution to the equation f(x)=g(x).

Answer 1

Answer: x = -3

The two diagonal lines cross at (-3,5). We only need to worry about the x coordinate here, so x = -3 is what we're after. If x = -3, then f(x) and g(x) have the same y output meaning f(x) = g(x). That y output is y = 5.
