Question 242795
Determine the equation of the line described. Put answer in the slope-intercept form, if possible. Through (1,-8), perpendicular to -7x-4y=25.
--------------
The given line has slope = -7/4
------------------------------------
A perpendicular line must have slope = 4/7
------------------------
Form: y = mx + b
m = 4/7 and y = -8 when x = 1
Solve for "b":
-8 = (4/7)*1 + b
b = -60/7
--------------------------
y = (4/7)x-(60/7)
