Wanda wants to write equations in the form y = mx + b for the lines passing through point p that are parallel and perpendicular to line u. first she finds the slope of line u and line q to be 12 and the slope of line z to be -2. point p is located at (-2, 1). which next step could she use to find the y-intercepts?

Anyone know? will mark brainliest if correct!
