graph: $f(x)=\\frac{1}{2}x - 2$
graph: $f(x)=\\frac{1}{2}x - 2$
Answer
Explanation:
Step1: Find the y - intercept
When (x = 0), substitute into (y=\frac{1}{2}x - 2). (y=\frac{1}{2}(0)-2=-2). So one point is ((0,-2)).
Step2: Find another point using the slope
The slope (m = \frac{1}{2}). From the point ((0,-2)), using the slope formula (m=\frac{\Delta y}{\Delta x}). If (\Delta x = 2), then (\Delta y=1). When (x = 2), (y=\frac{1}{2}(2)-2=1 - 2=-1). So another point is ((2,-1)).
Answer:
Plot the points ((0,-2)) and ((2,-1)) on the graph.
