Question

PLEASE HELP!!What is the slope of a line of best fit if its equation is y = 5x - 4?0-40-1O1505

Answer 1

Step 1

Given;

`y=5x-4`

Required; To find the slope

Step 2

The equation of a line is given as;

`\begin{gathered} y=mx+c \\ m=slope \\ c=y-intercept \end{gathered}`
`\begin{gathered} differentiating\text{ the given equation gives} \\ (dy)/(dx)=5 \\ comparing\text{ both equations give m=5} \end{gathered}`

Hence the slope of the line is;

`5`
