Question

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

y+1=6/7(+3)
y+3=7/6 (2+1)
y-1=6/7 (2-3)
y+1=6/5 (2+3)

Answer 1

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

Explanation:

First find the slope

m = (y2-y1)/(x2-x1)

= (-1-5)/(-3-4)

= -6/-7

= 6/7

Point slope form is

y-y1 = m(x-x1)

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

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