Question

Complete the equation for the linear function whose graph contains the points

(−1, −2) and (3, 10).



y + ? = ? (x + 1)
i know the slope is 3

Answer 1

@shamim the first one is 3, right?
but how do i find the second question mark?

Answer 2

nope first one is not 3

Answer 3

in order 1st value is x 2nd one is y \[\huge\rm (x_1 ,y_1) ( x_2 , y_2)\]

Answer 4

for 2nd question marks u have to use formula to find slope \[\huge\rm\frac{ y_2 -y_1}{ x_2 -x_1 }\] use that two order pair to find slope

Answer 5

for the first one i got 1/-7

Answer 6

nope first one is the y values form the order pair

Answer 7

they already gave u x_1
which one is 1 so you know that they are using first order pair
what is y in 1st order pair ??
