You can put this solution on YOUR website! Find the equation of the line which is parallel to the line y=-3x -7 and pass through points (3,0).
***
Equation of line: y=mx+b, m=slope, b=y-intercept
Given line: y=-3x -7
Slope of this line=-3
Slope of line parallel to given line=-3
equation of parallel line: y=-3x+b
solving for b using coordinates of given point on the line(3,0)
0=-3*3+b
b=9
Equation of parallel line:y=-3x+9
