Question

Write the slope-interference form of the equation of each line

Answer 1

The slope interference form of straight line is given by

`y=mx+c`

Here is the slope of the line and c is the y-intercept

Now, from the graph, it is seen that the line passes through the points (0,4) and (3,5)

So,

`\begin{gathered} (y-4)/(5-4)=(x-0)/(3-0) \\ (y-4)/(1)=(x)/(3) \\ 3(y-4)=x \\ 3y=x+12 \\ y=(x)/(3)+4 \end{gathered}`

So, the required equation is

`y=(x)/(3)+4`
