Answer:
x=2
Step-by-step explanation:
When you sub in these values for the pythagorean theorem you get 1.5^2+x^2=2.5^2
2.25+x^2=6.25
4=x^2
x=2
The function shown in the graph is a linear function, for a given linear function, the initial value is obtained at y-intercept. The y-intercept is the point where the graph cuts the y-axis. At this point the value of x is zero. Thus from the graph given, the point x=0 at y=2, hence the initial value is y=2.
Answer: y=2
