Answer:
y = x + 5
Step-by-step explanation:
Find any two points:
(1, 6)
(2, 7)
Slope = (y2 - y1) / (x2 - x1)
S0:
7 - 6 / 2 - 1
1 / 1
So slope = 1
Equation:
y = mx + b
Plug in the numbers using the x and y of any points:
7 = m * 2 + b
Add m (which is the slope):
7 = 1 * 2 + b
7 = 2 + b
Subtract two from both sides:
5 = b
So our equation is:
y = x + 5
Please let me know if I've done anything wrong!
So what you do is make a fraction with the conversation between miles and km with km on the bottom to cancel out the units and multiply the fraction by the amount of km
5km (.62miles/1km) = 3.1 miles
