Find the equation of the line that passes through the points (-8,4) and (5,-2)

Answer provided by our tutors

the equation of the line is:


y = mx + b, where "m" is the slope and "b" gives the y-intercept


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


m = (-2 - 4)/(5 - (-8))


m = -6/13


y = (-6/13)x + b


the line passes through the point (-8,4) means that for x = -8, y = 4


4 = (-6/13)(-8) + b


b = 4 - (-6/13)(-8)


b = 4/13


the equation of the line that passes through the points (-8,4) and (5,-2) is:


y = (-6/13)x + (4/13).
