Question

Graph the set of points. Which model is most appropriate for the set?

(-6,-1), (-3, 2), (-1, 4), (2, 7)

a. Linear
b. quadratic
c. exponential

Answer 1

The Answer is :

A. Linear

Answer 2

check the slope between the moving points

slope between (–6, –1) & (–3, 2) = 1
slope between (-3, 2) & (–1, 4) = 1
slope between (-1, 4) & (2, 7) = 1

the points are collinear and make an angle of 45 degrees with the x-axis

we can have an equation of a line passing through (-6,-1) and slope 1 as

(y + 1) = 1(x + 6)
y = x + 5 is your linear model mostly
