Answer:
Slope = 5. Equation is y = 5x + 1.
Step-by-step explanation:
We turn the given information into a point on the graph. y2-y1/x2 - x1.
So we have (1, 6) and (3, 16) --> (minutes, calories).
16-6 = 10. And 3 -1 = 2. 10/2 = 5. So the slope is 5.
I used the point slope form equation (its faster for me)
y - y1 = m(x - x1).
y - 6 = 5(x - 1) --> plug in the first point that we got from the given information
as y1 and x1.
y -6 = 5x -5. ---> use the distributive property.
y = 5x + 1 --> add 6 to both sides to put it into regular slope form
Now you have your equation for the line of best fit.
