Given
The slope of the line is 3.
And, the coodinates of x and y on the graph is (-1,1).
To find the equation of the line using slope point form.
Explanation:
The equation of the line using slope point form is given as,
[tex]y-y_1=m(x-x_1)[/tex]Then, for m=3 and point (-1,1).
We get,
[tex]\begin{gathered} y-1=3(x-(-1)) \\ y-1=3(x+1) \\ y-1=3x+3 \\ y=3x+3+1 \\ y=3x+4 \end{gathered}[/tex]Hence, the equation of the line is y=3x+4.
