Gradient =
This means the gradient is 4x.
The y intercept is where the line crosses the y axis. We can see this is at -3.
<h2>Rule: <u>y = 4x -3</u></h2>Substitute your values to check if it's right.
y = 4x -3
5 = 4(2) - 3
5 = 8 - 3
5 = 5
1 = 4(1) - 3
1 = 4 - 3
1 = 1
the slope or average rate of change for the trip from the graph is just rise/run. Now, let's take a look at those values to get it
so the slope of it is 1/5, 2 hours is 120 minutes, what would be the distance value on 120 minutes?
