The numerical expression that describes the amount of time it takes Imani to walk to school is x = 5y - 1.
<h3>How do we derive a numerical expression?</h3>
Let:
x = amount of time it takes Imani to walk to school
y = amount of time it takes Imani to ride to school = 3 minutes
The numerical expression that describes the amount of time it takes Imani to walk to school can be written as follows:
x = 5y - 1
Since it takes Imani three minutes to ride her bike to school, we can solve for x by substituting y = 3 as follows:
x = (5 * 3) - 1 = 15 - 1 = 14 minutes

Y = mx + b
m is your slope AKA rate of change
b is the y intercept.
from the graph we can see that the y intercept (b) is 15. (look at the y axis and see what point the line crosses on the y, here it is 15, in-between 10 and 20)
slope is rate of change. to figure this out remember slope = rise over run:

so pick two points. how much does one point rise after the other point you picked? In the graph it rises 1 square so rise = 1
Now looking at the same two points, how far away from each other are they on the x axis? Looking at the graph they are 2 squares away from each other. so run = 2
Now plug these numbers into the rise over run formula:

Now we have everything we need to put into our formula for a line:
