it would be 0.2 + 2.5 = 2.7 btw

1/5 + 5/2

= 2/10 + 25/10

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

VikaD [51]

Let's use the slope-intercept equation:

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

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

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