What is the constant of proportionality in the equation y
=
1
2
x
y=
2
1

xy, equals, start fraction, 1, divided by, 2, end fraction, x?

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!

So confused right here i need it to be more clearer
