Question 385134
Write the slope-intercept equation for the line that passes through (-7, 6) and is perpendicular to -7x + 9y = -2 Please show all of your work. can someone help me with this
...
-7x + 9y = -2
+7x
9y=7x-2
/9
y=(7/9)x-(2/9)
slope = 7/9
..
slope of line perpendicular will be (-9/7)
..
Point (-7,6) slope (-9/7)
find b in y = mx +b
6=(-9/7)*-7+b
6=9+b
b=-9+6
b=-3
...
The equation is 
{{{(highlight(y=(-9/7)x-3))}}}
