Grant wrote an equation of a line through the point (4,1) that is perpendicular to the one shown. What other point lies on his line?

I have to see the line shown. We need the slope of the line shown.
Grant's line will have a slope that is a negative reciprocal of the line shown.
for example if the line has a slope of 3, Grant's perpendicular line will be 1/3.
To find the other point, use the slope formula: m = (y2y1)/(x2x1)

Another approach is to use:
y = mx + b
You will have m, x and y.
solve for b.
Write an equation where you have a value for m and b.
You can then figure out another x and y that will work in that equation.
