Question

Write an equation in slope-intercept form of the line that passes through (4, 8) and (0, -2).
Answer

y = 5/2 x - 2

y = -5/2 x + 8

Y = 2/5 x - 6

y = -2/5 x + 4

Answer 1

slope = 8 +2 /4 = 10/4 = 5/2

y = mx + c
-2 = 0 + c

c = -2

equation = y = 5/2x - 2

Answer 2

slope formula : slope(m) = (y2 - y1) / (x2 - x1)
(4,8) -- x1 = 4 and y1 = 8
(0,-2) -- x2 = 0 and y 2 = -2

now les sub in our stuff and find the slope...
m = (-2 - 8) / (0 - 4)
m = -10/-4
m = 5/2

now we will use point slope formula :
y - y1 = m(x - x1)
(4,8) -- x1 = 4 and y1 = 8
slope(m) = 5/2

y - 8 = 5/2(x - 4)
y - 8 = 5/2x - 10
y = 5/2x - 10 + 8
y = 5/2x - 2

I agree with joel :)
