Answer:-2
Explanation:
Step 1: Write this in slope-intercept form
y=mx+b
Step 2: Plug in the known values
m is the slope, x is the given x value, and y is the given y value
4=2(3)+b
Step 3: Solve for the y-intercept
the y-intercept is b, so all we need to do is solve for b
4=6+b
subtract 6 from both sides so that y is isolated
Answer: b=-2
The y-intercept is -2
