Question

Does the following set of ordered pairs satisfy a linear function?
{(1, 8), (2, 6), (3, 4), (4, 2), (5, 0)

Answer 1

function because each input has only one output

linear because points fall on straight line

Answer 2

yes

Answer 3

yes, as x goes up by 1, y goes down by 2 each time. that's linearity!

Answer 4

yes they satisfy a linear function of equation
y=-2x+10

Answer 5

Yes, collinear points.

Answer 6

x values step up by 1 whilst y values step down by 2
