answer:
y=1x-50
Explanation:
y=mx+b
m=slope
b=y-intercept
x=unknown variable
to find the slope i used rise/run
my rise was 3 and my run was also 3
3÷3=1
the slope is going to the right making it positive
the y-intercept is -50 because that is where the line hits the y-axis
good luck :) hopefully this helps
have a great day !!
