Samantha got a bouquet of flowers. there are 2 daisies and 10 roses in the bouquet. what is the ratio of daisies to roses in the bouquet?

The ratio is 2:10, which is the exact same as 1:5. 
For every 2 daisies, there are 10 roses. So for every 1 daisy, there are 5 roses.

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!
