slope and y intercept form for x-2y=4

1 answer

To write the equation in slope-intercept form (y = mx + b), we need to isolate y on one side of the equation.

Given equation: x - 2y = 4

First, we can subtract x from both sides:
-2y = -x + 4

Next, divide both sides by -2:
y = (-1/-2)x + (4/-2)

Simplifying, we have:
y = (1/2)x - 2

Therefore, the equation in slope-intercept form is y = (1/2)x - 2.

The slope of the line is 1/2, and the y-intercept is -2.
