Question

What is the equation in point-slope form of the line passing through (–2, 1) and (4, 13)?

please help me

Answer 1

what is the slope ?

Answer 2

y – 1 = –2(x – 4)

y – 1 = 2(x + 2)

y – 13 = –2(x + 2)

y – 13 = 2(x + 4)

Answer 3

do you know what is the slope ?

Answer 4

no I dont unfortunatly

Answer 5

ok slope you use formula

y2 - y1
------
x2 - x1

you have points (-2,1) and (4,13) , can you plug in on formula
(x1,y1) (x2,y2)

Answer 6

i still dont get how to get to the answer after pluggin in and solving

Answer 7

13 - 1 12
----- = ---- = 2
4 + 2 6

so the slope = 2

Answer 8

the formula for the equation in point slope form

is y- y1 = m(x-x1) you have m= slope = 2, use points (-2,1) for (x1,y1)

what do you get ?

Answer 9

can you plug numbers in this formula, that will give you answer

Answer 10

y – 1 = 2(x + 2) ?

Answer 11

correct
