What is 21,800,00 written in scientific notation?

2.18 x 10^6

Just move the decimal to the front between the first two numbers and count how many places you moved it.

Make sure to mind your significant figures and don't put more than two digits after the decimal.

Note: You only have four zero in your question. If you meant five zeroes then your exponent changes by +1.

Distributive property

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!
