What is the y-intercept of the equation of the line that is perpendicular to the line y =
x + 10 and passes through the point
(15,-5)?
ov=x=20
ov=-*}x+20
v=5x=20
y=-3x +20

intercept

line

Step-by-step explanation:

Let is the required line.

Slope of perpendicular lines : If and be slope of two perpendicular lines. Them

is perpendicular to

the slope of  is

Hence eqn is

This equation passes through

so the line is

y-intercept :

Substitute

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )

just needed some points but try socratic
