Question

Written in slope-intercept form, the equation x + 2y = 4 is


2y = -x + 4
y = -1/2x + 4
y = -1/2x + 2

Answer 1

slope intercept form is y = mx + b

x + 2y = 4 (we want y term by itself, so subtract x from both sides)
2y = -x + 4 (now we need to divide by 2)
y = (-x + 4)/2 or y = -1/2x + 2
