Question 519457
Write an equation in slope intercept form satisfying the given conditions (Please?): 
The line passes through (4,-7) and is perpendicular to the line whose equation is x - 2y = 3. 
----
Determine the slope of the given line.
2y = x-3
---
y = (1/2)x - (3/2)
slope of the given line is 1/2
----
Therefore slope of any perpendicular line must be -2
====================
Form of needed equation: y = mx + b
y = -7 when x = 4 and the slope is -2
Solve for "b":
-7 = -2*4 + b
b = 1
------------------
Equation:
y = -2x +1
