On a map of downtown lineville, 12th street is perpendicular to avenue j. the equation y = -4x + 3 represents 12th street. what is the equation of avenue j if it passes through the point (8, 16)?
y = -4x + 48
y = -4x + 14
y = 1/4x + 3
y = 1/4x + 14

I'm so close to finishing all these.

In a certain pentagon, the interior angles are a, b,c, d,e where a, b,c, d,e are integers strictly less than 180. ("strictly less than 180" means they are "less than and not equal to" 180.) if the median of the interior angles is 61 and there is only one mode, then what are the degree measures of all five angles?

Roger and natalie travel in similar cars. roger's car drives the two miles to school in 7.5 minutes. natalie drives the same distance in the opposite direction but in only 6.5 minutes. what is true of their velocities?
