how do i find the equation of the line that passes through points
(3,1), (0,3), (-2,k) and how do i find its value of k?
:
Assuming it is a linear equation
Find the slope using the 1st two points
We know the y intercept from the 2nd point,(0,3)
:
m = =
:
The slope/intercept equation: y = x + 3
:
the 3rd point: (-2,k)
x = -2 and k=y, therefore
k = (-2) + 3
k = + 3
k = 1 + 3
k = 4
