Step-by-step explanation:
Answer:The distance from a point to a line is
distance(ax+by+c=0,(x0,y0)) = abs(ax0+by0+c)/sqrt(a^2+b^2)
So first convert the formula for the line to standard form
5x+2y=4
5x+2y-4=0
a=5, b=2, c=-4, x0=15, y0=-21
Step-by-step explanation:
Vertical line, because it doesn't have an x-coordinate unit of change so the line would just be straight and vertical along the graph (0, 7).
