Who's good in graphing? give brainlest and points

y=4/3x

Step-by-step explanation:

if you're looking for a perpendicular line then you must have the opposite reciprocal for the slope of your new line basically the slope must be flipped and the sign must change.

When you have that then you plug it into point slope form with your point that you want it to go through.

y-y1=m(x-x1)

looks like

y-12=4/3(x-9)

distribute 4/3 into the parenthesis

y-12=4/3x-12

add 12 to both sides

y=4/3x

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.

24

step-by-step explanation:

you just have to add the 15 + 9 to get 24

you do this bc you want to find the total of the whole line and those two numbers make up the line
