Graph f(x)=2x+3
Problem
Solution
Identify the function type, which is a linear function in the slope-intercept form
y=m*x+b Determine the y-intercept by looking at the constant term
b=3 which corresponds to the point(0,3) Determine the slope
m=2 which represents the "rise over run" ratio2/1 Find a second point by starting at
(0,3) and moving up2 units and right1 unit to reach(1,5) Draw the line through the points
(0,3) and(1,5) to complete the graph.
