Predict the yvalue if x = 3.
x: 1, 0, 1, 2.
y: 5, 3, 1, 1.
I thought was the x value was: 1, 0, 1, 2? Not x=3.... how can this be?
?????? Please help :(

Best ResponseYou've already chosen the best response.1you have a constant difference between y values, can you spot that difference?

Best ResponseYou've already chosen the best response.0the difference in x's pattern is adding 1 from 1. in y's pattern it's by adding 2 from 5. is that what you were asking?

Best ResponseYou've already chosen the best response.1yes, thats what I was asking; since y changes by 2 when x changes by +1 we can create a slope by stacking y/x slope = 2/1, or simply 2 notice that when x=0 we have a y value, known as the y intercept value; do you see it?

Best ResponseYou've already chosen the best response.1using a slope intercept from of a line: y = mx+b we can construct a model to predict the unknown value y = 2x +3

Best ResponseYou've already chosen the best response.1otherwise, we could have simply went backwards from 5 to get 2 extra spots 3 2 1 9 7 5 +2 +2
