Morita works in a florist shop and makes flower arrangements. she puts 10 flowers in each vase, and 2/10 of the flowers are daisies. if morita makes 4 arrangements, how many daisies does she need?

In each arrangement, there are 10 flowers. The daisies are 2/10. multiplying 2/10 to 10, we get 2. So there are 2 daisies.

If Morita makes 4 arrangements, then the number of daisies she needs is 
= 4 * 2
= 8

So she need 8 daises for here 4 arrangements.

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!
