The line equation is .
First find the x-intercept, let y = 0.
(Replace y with 0)
(Divide each side by 5)
(Simplify)
Since x = 0 when y = 0 graph the ordered pair (0, 0)
To find the y-intercept, let x = 0.
(Replace x with 0)
(Simplify)
Since y = 6 when x = 0 graph the ordered pair (0, 6)
Use these ordered pairs to graph the equation.
- Draw a coordinate plane.
- Plot the points (6, 0) and (0, 6)
- Draw a line through these points.
Check:
Check by solving the equation for y.
(Write the equation)
(Subtract x from each side)
(Simplify)
If x = 4,
(Subtract: )
Notice that the graph of (4, 2) is on the line.
