Question

Write the equation of the line that passes through the points (–1, –4) and (2, 5) in point-slope form.

Answer 1

first you need to find the slope using formula

Answer 2

(2 , 5)
(–1, –4)
---
3,9;slope=9/3=3

the equation of the line is: y = mx -mPx + Py , where (Px,Py) is any point that is given

and m=slope
y = 3x -3(2)+5

y = 3x -6+5 did

y = 3x -1 did i do it right ?
instruction asks me this -->
Part 1: Write the equation of the line that passes through the points (–1, –4) and (2, 5) in point-slope form.

Part 2: Using complete sentences, explain whether or not it matters which point is used in the final answer. Also explain why you chose the point you did.

Answer 3

yes that is correct y = 3x -1

Answer 4

Im really stuck on part 2 :((

Answer 5

the equation of the line is y = 3x -1, that means that the slope = 3 and the y-int = -1
the line have many points (x,y), so it doesn't really matters what point you used.

Answer 6

Thank You So Much Best Answer !!

Answer 7

you can said that you chose point (2,5) because it was easier for you to deal with positive integers.
