the formula y-y=m(x-x) is the point -slope from of the equation of a line where m is the slope of the line and (x,y) and ( x,y) are points of the line. solve the equation for m and find the slope of a line that includes the points ( 4-2) and ( 5,0)

Respuesta :

(4,-2)(5,0)
slope(m) = (0 - (-2) / (5 - 4) = 2/1 = 2
there is going to be 2 possible answers...

y - y1 = m(x - x1)
now we sub

using points (4,-2)..... y -(-2) = 2(x - 4) =
y + 2 = 2(x - 4) <==

using points (5,0)....y - 0 = 2(x - 5) <==
