Answer:


y\text{ = 3x-21}

Step-by-step explanation:

Here, we want to get the equation of the line

Mathematically, we have the equation of a straight line as:


y\text{ =mx + b}

where m is the slope and b is the y-intercept

From what we are given , the slope is 3

To the x-intercept, it is the value of x when y = 0. We can use this to get b

Mathematically, we have that as:


\begin{gathered} 0\text{ = 3(7) + b} \\ 0\text{ = 21 + b} \\ b\text{ = -21} \end{gathered}

The equation of the line is:


y\text{ = 3x-21}
