Answer:
m = -4
b =1
y = -4x+1
Explanation:
We want to find the slope and y intercept
Given the two points ( -1,5) and ( 1,-3), we can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( -3 -5)/( 1 - -1)
= -8/( 1+1)
= -8/2
= -4
The y intercept is where it crosses the y axis
It crosses at 1
The slope intercept form of the line is
y = mx+b
y = -4x+1
