Answer:
-5
Step-by-step explanation:
First, we can plug all the given values into the equation y=mx+b. This is called slope-intercept form. m is the slope and b is the y-intercept. To find the y-intercept, we solve for b.
y=mx+b
1=2(3)+b
1=6+b
Subtract both sides by 6
1-6=6+b-6
-5=b
Therefore, the y-intercept is -5.
