Question

Write an equation of a line in slope intercept form going through the points (2, 1) and (- 1, - 5). Show your work

Answer 1

first we need to find the slope(m)...
m = (y2 - y1) / (x2 - x1)
x1 = 2, x2 = -1
y1 = 1, y2 = -5
lets sub it in...
m = (-5 - 1) / (-1 - 2)
m = -6/-3 = 2
so our slope is 2

y - y1 = m(x - x1) using slope 2 and points (2,1)
y - 1 = 2(x - 2)
y - 1 = 2x - 4
y = 2x - 4 + 1
y = 2x - 3 <-- your equation
