Graph -x+3y=6
Problem
Solution
Identify the equation as a linear equation in two variables, which represents a straight line.
Solve for y to put the equation into slope-intercept form,
y=m*x+b wherem is the slope andb is the y-intercept.Add x to both sides of the equation.
Divide every term by 3 to isolate
y
Determine the y-intercept by looking at the constant term. The y-intercept is
(0,2) Determine the slope by looking at the coefficient of
x The slope ism=1/3 meaning the line rises 1 unit for every 3 units it moves to the right.Find the x-intercept by setting
y=0 in the original equation.
Plot the points
(−6,0) and(0,2) on a coordinate plane and draw a straight line through them to complete the graph.
