Question

Write an equation for this line-Please be quick, I'm in a hurry

Answer 1

The equation of a line is given by the equation;

`\begin{gathered} y=mx+c \\ m\colon\text{slope} \\ c\colon\text{intercept on y-axis} \end{gathered}`

From the given graph, the intercept on y-axis is 7.

To find the slope, we would make use of the slope formula given as:

`m=(y_2-y_1)/(x_2-x_1)`

From the graph, we have:

`\begin{gathered} m=(22-8)/(12-1) \\ m=(14)/(11) \\ m=1.273 \end{gathered}`

Hence, the equation of the line is:

`y=(14)/(11)x+7`
