Akennel has 80 dogs in total, some are puppies and some are adult dogs. the ratio of puppies to dogs in a kennel is 3 : 2. how many puppies are there?

put how you solved this.

Answer : 48

Workings : add the two ratios together (3 + 2 = 5) then do 80 divided by 5 = 16 and then times 16 by the puppy part of the ratio which is 3. This equals 48

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!
