<PRE><B>Question 326967</B>
write the equation of a line in slope-intercept form that 
passes through (-1,7) and (-2,-15)?
------------------
slope = m = (-15-7)/(-2--1) = -22/-1 = 22
------------------------------------------------
Form: y = mx + b where m=22 and y = 7 when x = -1.
---
7 = 22(-1) + b
b = 29
---------
Equation:
y = 22x + 29
