Use the given conditions to write an equation for the line in point-slope form. Passing through (-5, -7) and (-8, -6) I honestly cant do these, they confuse me
I have multiple choices , I just don't know:(
A. y - 7 = -1/3 (x - 5) or y - 6 = -1/3 (x - 8) B. y + 7 = -1/3 (x + 8) or y + 6 = -1/3 (x + 5) C. y + 7 = -1/3 (x + 5) or y + 6 = -1/3 (x + 8) D. y + 7 = -1/3 x - 5 or y + 6 = -1/3 x + 7

point slope equation (y-y1) = m(x-x1) (x,y) any point (x1,y1) point on the line m= slope
I got c as my answer
slope m = y2 -y1/x2-x1 the 2 given point (x1, y1) and (x2, y2)
(-5,-7) (-8,-6)
-6- -7/-8 - -5?
(-5, -7) and (-8, -6) m = -6 --7/-8--5 = -6 +7/(-8 + 5) = 1/-3 = -1/3 y --6=-1/3(x --8) y + 6 = -1/3x + 8/3 y = -1/3x +8/3-18/3 =-1/3x -10/3 point-slope form yes c
sorry here are the steps 2 points on the line find the slope slope = change in y / CORRESPONDING change in x (y2-y1)/(x2-x1) using any one of the given points find the equation for any point (x, y) equation (y-y1)= m(x-x1) where (x1,y1) is a point on the line same line if you use (x2, y2) any questions?
