Question

Find the slope-intercept of a line with the following points (-1,2) and (1,-1)

Answer 1

first find the slope from these points
can you???

Answer 2

M = (-1 - 2) / (1 + 1)
M = -3 / 2
M = -1.5?

Answer 3

yes exactly

Answer 4

now use point slope form to get the equation

Answer 5

how do i find x and b?

Answer 6

using this formula you will get it
y-y1 = M (x-x1)

Answer 7

so y - 2 = -1.5(x + 1)
y = -1.5x + 2?

Answer 8

right , but instead of 2 it will be 0.5

Answer 9

y = -1.5x + 0.5

Answer 10

yes this man right

Answer 11

@rizwan_uet , I'm a girl :P
