Identify the correct slope and y intercept of the equation 2x + 4y = 12.

How would I do this?

slope = 2; y intercept at (0, 12)

slope = 1/2; y intercept at (0, 3)

slope = 1/2; y intercept at (0, 4)

slope = - 1/2; y intercept at (0, 3) ... ?

The standard form of a line is an easy way to solve for the properties of a line, such as slope and the intercepts. Take a line with the equation in standard form,

Ax + By = C

The slope here is given by y = - A/B.

The x-intercept here is given by (C/A, 0).

The y-intercept here is given by (0, C/B).

For this problem, the equation is 2x + 4y = 12. Thus,

slope = - 2/4 = - 1/2

y-intercept = (0, 12/4) = (0, 3)
