What is (1, 7.7) and (6, 9.2), where x represents the number of weeks, and y represents the baby's weight, in pounds. Thanks
I am assuming that you want to write an linear equation to model this. Let's find the slope, first. We have...
(9.2 - 7.7) / (6 -1) = 1.5/5 = 3/10
So....using the point-slope form, we have
y - 7.7 = (3/10) (x - 1) simplify
y = .3x - .3 + 7.7
y= .3x + 7.4
Here's a graph.......https://www.desmos.com/calculator/bqjdf69f6j
Of course, the graph is only good for x ≥ 0
