y=-2x+5

Step-by-step explanation:

2y-1x=10    (1,3)

A perpendicular slope would be the opposite sign (+or-) and be a reciprocal (flip numerator and denominator) We will ignore the 5 for now because we need to find the b

First, let's turn this into slope-intercept form:

2y=1x+10 divide both sides of the equation by 2

y=1/2x+b because we want the perp. we will use y=-2x+b

Let's plug in the (x,y)

3=-2(1)+b  

3=-2+b   add 2 to both sides

5=b   so our equation is y=-2x+5
