Question

Find the equation of each line with the following general informatie (c) r-intercept a and slope m (d) inclination and y-intercept b

Answer 1

Let's use the slope-intercept equation:

`\begin{gathered} y=mx+b \\ m=slope \\ b=y-intercept \\ x-intercept=a \\ x=(y-b)/(m) \\ x=(y)/(m)-(b)/(m) \\ x=(y)/(m)-a \\ or \\ y=mx+ma=m(x+a) \end{gathered}`

------------------------------------

d)

`\begin{gathered} y=mx+b \\ m=slope=\theta \\ b=y-intercept \\ y=\theta x+b \\ \end{gathered}`
