Question

use the intercepts to graph the equation
x+2y=4

Answer 1

1. solve for y
y = (4-x)/2

2. replace x with zero, find y: y = 2...so the first point is (0,2)
3. replace y with zero, find x: x = 4...so the second point is (4,0)
4. Plot these points on an xy plane, connect them with a straight edge and draw a line though them
