how do i do this!? please help!
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

Well the formula is,

$$(y-y_1)=\frac{ y_2-y_1 }{ x_2-x_1 }(x-x_1)$$

To find the answer you should use y = mx + b
To find M use the formula: $$\frac{ y2-y1 }{ x2-x1 }$$
Then, to find B, use $$b = y1 - mx1$$
Finally, put it all together.
