Answer:
y = 4x + 3
Step-by-step explanation:
The output of 3 at x = 0 tells you the y-intercept is 3.
The change of 4 from 3 to 7 for an input change of 1 from 0 to 1 tells you the slope is 4/1 = 4. Then the slope-intercept form of the equation is ...
y = mx + b . . . . . m = slope, b = y-intercept
y = 4x + 3
_____
It is pretty conventional to use y for the output variable and x for the input variable. Your rule could be ...
output = 4 × input + 3
First, find her rate for the day. Since she runs 10 laps a day, multiply.
400 times 10= 4000
Next, I'll convert kilometers into meters;
12 times 1000=12,000
Divide to find the days:
12,000/4,000=3
It will take 3 days to run a total of 12 kilometers.
