Question

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

ivettef365 · Answer

what is the slope ?

anonymous · Answer

y – 1 = –2(x – 4) 

 y – 1 = 2(x + 2) 

 y – 13 = –2(x + 2) 

 y – 13 = 2(x + 4)

ivettef365 · Answer

do you know what is the slope ?

anonymous · Answer

no I dont unfortunatly

ivettef365 · Answer

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)

anonymous · Answer

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

ivettef365 · Answer

13 - 1          12
-----  =    ----   = 2
4 + 2              6

so the slope = 2

ivettef365 · Answer

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 ?

ivettef365 · Answer

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

anonymous · Answer

y – 1 = 2(x + 2) ?
