Given a sketch of a linear graph solve f(x) = n This is the graph of
\[
y=0.5 x-2
\]

According to the graph, what is the solution to:
\[
0.5 x-2=1
\] ![Graph showing straight line with y intercept (0,-2) and x intercept (4,0)]() \( x=4 \)
gpt
Believes the solution to mx + c = a is the x intercept of y = mx +c
