Question

What is y=-10x's constant of proportionality and how would describe a graph's constant rate of change.

Answer 1

Okay, so here, we know that -10 is the slope, therefore, it is also the constant of proportionality.

'x' is the unknown value, that tells us to multiply by -10.

So, on a graph, we would consider that per unit, it would decrease by -10, since its a negative slope.
