Question

i will give a medal if you can help me with this one problem!!!geometry
13.Write an equation in point-slope form of the line throught J(4,1) with slope -4.
if you dont want to answer it atleast walk me through it please!!:)

Answer 1

I'll walk you through it. So what does the point-slope form look like?

Answer 2

all i know is the given information -Write an equation in point-slope form of the line throught J(4,1) with slope -4.
i dont know how to write the equation in point-slope form

Answer 3

so point- slope form is given by this formula: \[y-y_{1} = m(x - x_{1})\]
where m is the slope and x1,y1 is a point on the line. So given that information can you write the solution to your problem?

Answer 4

would it be y-4=-4(x-1)?

Answer 5

close! you switched the x and y coordinates!

Answer 6

so y-=-4(x-4)?

Answer 7

y-1=-4(x-4)?***

Answer 8

exactly good job!

Answer 9

thank you so much!!:)

Answer 10

no problem
