Question 125622
ok
so perpendicular lines have negative reciprocals so our slope is -4/5

now we substiutute the points in the slope to find the y intercept


so

y = m x +b
8= -4/5(1) +b
8= -4/5 +b
8-4/5= -4/5+4/5 +b
40-4/5 =b
-36/5 =b


so our y intercept i -36/5


so our equation is y=-4/5x+-36/5


Did this help?
