Question 799609: Find the equation of a line with the given information:
f(-13) = 6 and perpendicular to 32x+40y=38
Write your answer in point-slope form. If your answer is a vertical line, type your answer as x=#, and if your answer is a horizontal line, type your answer as y=#
Write your answer in slope-intercept form. If your answer is a vertical line, type your answer as x=#, and if your answer is a horizontal line, type your answer as y=#
Write your answer in function form. If your answer is a vertical line, type your answer as x=#, and if your answer is a horizontal line, type your answer as y=#

You can put this solution on YOUR website! Find the equation of a line with the given information:
f(-13) = 6 and perpendicular to 32x+40y=38
--------
40y = -32x + 38
-----
y = (-4/5)x + (38/40)
------
slope = -4/5
------
The perpendicular line must have slope = 5/4
---------------
Find equation of line with slope = 5/4 passing thru (-13,6)
----
y = mx + b
6 = (5/4)(-13) + b
24/4 = -65/4 + b
b = 89/4
======
Equation:
y = (5/4)x + (89/4)
--------------------------
