Question

1) Functions A, B and C are all linear functions ofx. Rank the rates of change and the y-intercepts of all three from smallest to largest. Function A Function B y = .5x. 0.55 X 0 1 2 3 у -1.25 0.5 0.25 1 1.75 Function C Rates of change in order smallest to largest : 3- + Y-intercepts in order smallest to largest: -1 -3​

Answer 1

Explanation:

slope = rate of change

y = mx + b ( "m" is slope, "b" is y-intercept)

(
`x_(1)` ,
`y_(1)` )

(
`x_(2)` ,
`y_(2)` )

m =
`(rise)/(run)` =
`(y_(2) -y_(1) )/(x_(2) -x_(1) )`
