Is it true 90 is 10 times a much as 0.9

Yes it is true that 90 is 10x as much as 0.9

NO that statement is not true because if you multiply 0.9 by 10 you get 9. 90 is 100 times as much as 0.9.

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!
