Answer:
y = -1x + 1
Explanation:
Calculate the slope from two points:
I picked (0,1) and (4,-3)
Rise = (-3 - 1) = -4
Run = (1 - 0) = 4
Slope or Rise/Run = -4/4 or -1
y = mx + b, where m is the slope and b is the y-intercept (the value of y when x = 0). We can find the y-intercept since we have point (0,1). b is 1.
Putting the slope and y-intercept into the equation:
y = -1x + 1
