new slope = -1/old slope
so for the first one
y = +(1/2) x + b
now put in 1 for x and 4 for y to find b
Do the second one the same way
1. Write an equation of the line that passes through point P and is perpendicular to the line with the given equation P(1,4); Y= -2x +4
2. Write an equation of the line that passes through point P and is perpendicular to the line with the given equation P(5,3); Y= 5x +2
4 answers
The equation for number 1. would be
Y= 1/2 x + 3.5?
The equation for 2. would be
Y= - 1/5 x + 4?
Y= 1/2 x + 3.5?
The equation for 2. would be
Y= - 1/5 x + 4?
yes, although I would write #1 as 2y = x + 7
and
yes again but again I would write 5y = -x + 20
and
yes again but again I would write 5y = -x + 20
I don’t understand why do you wirte it like that?
