which is an equation in point-slope form of the line that passes through the points (4,5) and (-3,-1)?


A. y+1=6/5(x+3)



B. y-1=6/7(x-3)


C. y+1=6/7(x+3)


D. y+3=7/6(x+1)

(4,5),(-3,-1)
slope = (-1 - 5) / (-3 - 4) = -6/-7 = 6/7

y - y1 = m(x - x1)
slope(m) = 6/7
using points (-3,-1)...x1 = -3 and y1 = -1
now we sub...pay attention to ur signs
y - (-1) = 6/7(x - (-3) =
y + 1 = 6/7(x + 3) <===
