Question

help porfavore!! What is the equation in point-slope form of the line passing through (–1, 3) and (1, 7)?
y – 7 = 4(x – 1)

y – 7 = 2(x – 1)

y – 3 = 2(x – 1)

y – 3 = 4(x + 1)

Answer 1

to solve this just plug in values into this equaiton


\[y _{2}-y _{1}= (y _{2}- y _{1}/x _{2}- x _{1})(x _{2}-x _{1})\]

Answer 2

?

Answer 3

do you get that? Its the point slope form and the fact that m = (Y_2-Y_1)/(x_2-(x_1)

Answer 4

???

Answer 5

i dont get it
:/

Answer 6

do you know th point slope formula

Answer 7

yes
