You are 9 miles away from home. You start biking home at a speed of 6 miles per hour.
1 answer:
A) y=9-6x, standard form is ax+by=c so add 6x to both sides
6x+y=9
b) from the first, we had it in slope intercept form, mx+b where b is the y-intercept. y=-6x+9
So the y-intercept is the point (0,9) which represents the starting distance before you start biking. You start being 9 miles from your house.
c) The x intercept occurs when y=0 so:
y=9-6x, so if y=0
0=9-6x
6x=9
x=9/6
x=1.5
This represent the time when you will arrive home and the total time that has elapsed to get there.
