Question

Which represents the equation of the side that is parallel to side r? Y = negative x + 9 y = negative x + 5 y = x minus 3 y = x + 3

Answer 1

y = x-3

Explanation:

Given the coordinate of the line s as (6, 3) and (4,1). Get the equation of this line;

Slope m = 1-3/4-6

Slope m = -2/-2

Slope m = 1

Using the pont slope form y-y0 = m(x-x0)

Substitute m = 1 and any point say (4, 1) into the equation above;

y - 1 = 1(x-4)

y-1 = x-4

y-x = -4+1

y-x = -3

y = x - 3

Hence the required equation is y = x-3
