Answer #4 please
It's called the "y intercept" and it's the y value of the point where the line intersects the y- axis.
For this line, the y-intercept is "negative 1." You can find the y-intercept by looking at the graph
and seeing,which point crosses the y axis. This point-will always have an x coordinate of zero.

Write the function that describes the car's distance from Yuma.
5. Two sailboats are traveling along the same path away from a
dock, beginning from different locations at the same time.
John's boat begins 30 miles from the dock and is 50 miles from
the dock after 5 hours. The distance of Roberta's boat from the
dock is represented by the function y = 5x + 25, where x
represents time and y represents the distance from the dock.
