Hi Michelle;
y=53x...(2,4)
The slope of the presented equation is 3. This is the coefficient of x. The line perpendicular to such is its negative inverse, 1/3
y=(1/3)x+b
This equation is in the slopeintercept format of...
y=mx+b
m is the slope.
b is the yintercept, the value of y when x=0.
We can proceed by pluggingin the coordinate provided and thereby establishing b.
Or, we can proceed by using the pointslope formula...
(yy_{1})=m(xx_{1})
y4=(1/3)(x2)
y+4=(1/3)(x2)
y+4=(1/3)x(2/3)
y=(1/3)x(4 2/3)
