Graph f(x)=2x-3
Problem
Solution
Identify the type of function. This is a linear function in the slope-intercept form
ƒ(x)=m*x+b Determine the y-intercept. The constant term is
−3 so the graph crosses the y-axis at the point(0,−3) Identify the slope. The coefficient of
x is2 which means the slopem=2/1 Apply the slope to find a second point. Starting from
(0,−3) move up2 units and right1 unit to reach the point(1,−1) Draw a straight line passing through the points
(0,−3) and(1,−1) to complete the graph.
