In an additive relationship of the form y = mx + b, the y-intercept is the point where the line intersects the y-axis. In this case, the equation is y = x + 7, so the y-intercept is when x = 0.
To find the value of y when x = 0, substitute x = 0 into the equation:
y = 0 + 7
y = 7
Therefore, the y-intercept is the point (0, 7).
Determine the y -intercept, b , of the additive relationship y=x+7 . Write as an ordered pair
