Answer:

Use the general point-slope formula

+%28+y+-+%28-7%29+%29+%2F+%28+x+-+%28-8%29+%29+=+5%2F4+

+%28+y+%2B+7+%29+%2F+%28+x+%2B+8+%29+=+5%2F4+

+4%2A%28+y+%2B+7+%29+=+5%2A%28+x+%2B+8+%29+

+4y+%2B+28+=+5x+%2B+40+

+4y+=+5x+%2B+12+

+y+=+%285%2F4%29%2Ax+%2B+3+

-----------------------------

check:

does it go through ( -8, -7 )?

+-7+=+%285%2F4%29%2A%28-8%29+%2B+3+

+-7+=+-10+%2B+3+

+-7+=+-7+
