Answer: y= -4x + 1
Step-by-step explanation:
(-1,5) (1,-3)
5-(-3)=8
-1-1=-2
8/-2=-4 negative 4 is the slope. Now find the y-intercept using the formula y=mx + b where b is the y intercept.
so we will plot the y and x values plus the slope to find the y-intercept.
5=-4(-1) + b solve for b
5=4 + b
b=1
so now will write the equation y = -4x +1
