Which equation represents a line that intersects the line 2y − 4x = 3?
a. -2y + 4x = 1
b. 3y − 6x = 6.5
c. y − 2x = 3
d. -2y − 4x = 3

Convert all the equations to slope-intercept form:





If two lines have the same slope, they're parallel and don't intersect.
The slope of the given line is 2.
The slopes of lines A, B and C are also equal to 2, so they are all parallel.
The slope of line D is -2, so it intersects the given line.
The answer is D.
