Transcript text: Find the graph for this direct variation equation.
\[
y=x
\]
Solution
Solution Steps
Step 1: Analyze the equation
The given equation is y = x. This is a linear equation with a slope of 1 and a y-intercept of 0. This means the line passes through the origin (0,0) and for every 1 unit increase in x, y also increases by 1 unit.
Step 2: Evaluate the graphs
The middle graph represents the equation y = x. It passes through the origin and has the correct slope. The first graph is y=1, and the third represents y=-x.
