Question

x y4 612 816 928 12based on the information in the table,what are the y intercept and slope of the line described by these points.A y intercept: 2; slope : m=4B y intercept : _ 20; slope : m = 1/4C y intercept : 5 ; slope : m =4D y intercept : 5 ; slope m = 1/4

Answer 1

`\begin{gathered} m=(y_2-y_1)/(x_2-x_1) \\ m=(8-6)/(12-4) \\ m=(2)/(8) \\ m=(1)/(4) \end{gathered}`

then for y intercept:

`\begin{gathered} y=mx+b \\ 6=(1)/(4)(4)+b \\ 6=1+b \\ 6-1=1+b-1 \\ 5=b \end{gathered}`

answer:

y intercept 5

slope m = 1/4
