Please answer I need help

Answer:
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
