Square EFGH is drawn on a coordinate plane. Diagonal GE is on the line y − 3 = 3(x + 4). What is the slope of diagonal FH? A) negative one third B) one third C) −3 D) 3

A) -1/3

Step-by-step explanation:

Diagonals in a square intersect at 90° angles, so they are perpendicular. Their slopes will be negative reciprocals. When y - 3 = 3 (x + 4) is written in y = mx + b form, the slope is 3. -1/3 is the negative reciprocal of 3.

3

Step-by-step explanation:

The slopes for diagonal GE and diagonal FH are the same.

y - 3 = 3(x+4)

Distribute

y - 3 = 3x + 12

Add 3 to both sides

y = 3x + 15

The number with x after it is the slope

The slope for diagonal GE is 3

Since diagonal GE and diagonal FH have the same slope, diagonal FH has a slope of 3.
