there can be 2 answers to this...depending on the point u use... y - y1 = m(x - x1) slope(m) = 5/3 using point (-4,15)...x1 = -4 and y1 = 15 now we sub y - 15 = 5/3(x - (-4)..not done yet y - 15 = 5/3(x + 4) <=== this is one answer
y - y1 = m(x - x1) slope(m) = 5/3 using point (-7,10)....x1 = -7 and y1 = 10 now we sub y - 10 = 5/3(x - (-7)...not done yet y - 10 = 5/3(x + 7) <=== and here is the other answer
