Write the slope-intercept equation for the line that passes through (10, 12) and is perpendicular to 5x + 8y = 1 Please show all of your work.
...
passes through (10, 12) and is perpendicular to 5x + 8y = 1
...
5x + 8y = 1
..
-5x
8y=-5x+1
/8
y=(-5/8)x+(1/8)
...
compare with y= mx +b
slope m= -5/8
..
perpendicular line will have slope of 8/5.
...
passes through (10, 12) slope 8/5
...
find b in y = mx+b
12=10*8/5 +b
12=16+b
b=-4
...
equation will be
m= 8/5, b =-4
...
%28highlight%28y+=+%288x%2F5%29-4%29%29 is the equation
...
