Iam a number that rounds to 30. what number could i be? could i be a different number? explain your thinking

Well any number that would round to 30 has to be over 25 so if that's all the information they give you, the number can we any where from 25 to 29.999... Also saying that it could be a different number

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!

The variables should add up to equal 1
