Question

Write an equation in slope-intercept form of the line that passes through (4, 8) and (0, -2).
A. y = 5/2 x - 2
B. y = -5/2 x + 8
C. y = 2/5 x - 6
D. y = -2/5 x + 4

Answer 1

\[\LARGE (y-y_1)=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\]

substitute..

\[\LARGE x_1=4, \quad x_2=0, \quad y_1=8 ,\quad y_2=-2\]
and there you go..
