Hope this help if you need help graphing I would use desmos
A line is perpendiculat to another which has a slope of m if the perpendicular line has a slope of -1/m.
That means that if the product of slopes of two lines is -1, the two lines are perpendicular.
Here, y1=-7/4x, or m=-7/4
The perpendicular should have a slope of -1/m=-1/(-7/4)=4/7
<span>so your equation would be 2x-3=-1 then your answer would be -1

As there is no x axis it will have to be vertical as the y axis is already vertical
