y = -4x -1
Explanation:
slope intercept form:
y = mx + b where m is the slop e and b is the y intercept
slope = (y2-y1)/(x2-x1)
Pick any 2 pts ont he line:
(-1,3) and (0,-1)
slope = (3- -1) / (-1 - 0)
= (3+1) / -1
=4/-1 = -4
the graph shows us the y intercept (b) is -1
So the equation is:
y = -4x -1
